TPS54335ADDAR SOP-8 Electronic components integrated circuit Voltage chip
TPS54335ADDAR
ACTIVE
4.5V to 28V Input, 3A, Synchronous, Step-Down Converter with Eco-modeThe TPS5433xA family of devices are synchronous converters with an input-voltage range of 4.5 to 28 V. These devices include an integrated low-side switching FET that eliminates the need for an external diode which reduces component count.
Efficiency is maximized through the integrated 128-mΩ and 84-mΩ MOSFETs, low IQ and pulse skipping at light loads. Using the enable pin, the shutdown supply current is reduced to 2 μA. This step-down (buck) converter provides accurate regulation for a variety of loads with a well-regulated voltage reference that is 1.5% over temperature.
Cycle-by-cycle current limiting on the high-side MOSFET protects the TPS5433xA family of devices in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. A low-side sinking current-limit turns off the low-side MOSFET to prevent excessive reverse current. Hiccup protection is triggered if the overcurrent condition continues for longer than the preset time. Thermal shutdown disables the device when the die temperature exceeds the threshold and enables the device again after the built-in thermal hiccup time.

Integrated Power Management IC (PMIC) w/ 4 DC/DCs, 8 LDOs and RTC in 6x6mm QFN familyThe TPS65910 device is an integrated power-management IC available in 48-QFN package and dedicated to applications powered by one Li-Ion or Li-Ion polymer battery cell or 3-series Ni-MH cells, or by a 5-V input; it requires multiple power rails. The device provides three step-down converters, one step-up converter, and eight LDOs and is designed to support the specific power requirements of OMAP-based applications.
Two of the step-down converters provide power for dual processor cores and are controllable by a dedicated class-3 SmartReflex interface for optimum power savings. The third converter provides power for the I/Os and memory in the system.
The device includes eight general-purpose LDOs providing a wide range of voltage and current capabilities. The LDOs are fully controllable by the I2C interface. The use of the LDOs is flexible; they are intended to be used as follows: Two LDOs are designated to power the PLL and video DAC supply rails on the OMAP-based processors, four general-purpose auxiliary LDOs are available to provide power to other devices in the system, and two LDOs are provided to power DDR memory supplies in applications requiring these memories.
In addition to the power resources, the device contains an embedded power controller (EPC) to manage the power sequencing requirements of the OMAP systems and an RTC.

TPS40200DR SOP-8 Electronic components integrated circuit 500kHz 4.5V-52V Switch controller DC-DC
TPS40200DR
ACTIVE
Wide Input Non-Synchronous Buck DC/DC ControllerThe TPS40200 is a flexible, non-synchronous controller with a built-in 200-mA driver for P-channel FETs. The circuit operates with inputs up to 52 V with a power-saving feature that turns off driver current once the external FET has been fully turned on. This feature extends the flexibility of the device, allowing it to operate with an input voltage up to 52 V without dissipating excessive power. The circuit operates with voltage-mode feedback and has feed-forward input voltage compensation that responds instantly to input voltage change. The integral 700-mV reference is trimmed to 2%, providing the means to accurately control low voltages. The TPS40200 is available in an 8-pin SOIC and an 8-pin VSON package and supports many of the features of more complex controllers. Clock frequency, soft-start, and overcurrent limits are each easily programmed by a single, external component. The part has undervoltage lockout, and can be easily synchronized to other controllers or a system clock to satisfy sequencing and/or noise-reduction requirements.

ACTIVE
Automotive 3.5-V to 36-V, 3-A synchronous step-down converterThe LM53603-Q1, LM53602-Q1 buck regulators are specifically designed for automotive applications, providing an output voltage of 5 V or 3.3 V (with ADJ option) at 3 A or 2 A, from an input voltage of up to 36 V. Advanced high-speed circuitry allows the device to regulate from an input of up to 20 V, while providing an output of 5 V at a switching frequency of 2.1 MHz. The innovative architecture allows the device to regulate a 3.3 V output from an input voltage of only 3.5 V. All aspects of this product are optimized for the automotive customer. An input voltage range up to 36 V, with transient tolerance up to 42 V, eases input surge protection design. An open drain reset output, with filtering and delay, provides a true indication of system status. This feature negates the requirement for an additional supervisory component, saving cost and board space. Seamless transition between PWM and PFM modes, along with a no-load operating current of only 24 µA, ensures high efficiency and superior transient response at all loads.

LM22672MRX-ADJ/NOPB
ACTIVE
SIMPLE SWITCHER® 4.5V to 42V, 1A Step-Down Voltage Regulator with Adjustable FrequencyThe LM22672 switching regulator provides all of the functions necessary to implement an efficient high voltage step-down (buck) regulator using a minimum of external components. This easy to use regulator incorporates a 42 V N-channel MOSFET switch capable of providing up to 1 A of load current. Excellent line and load regulation along with high efficiency (> 90%) are featured. Voltage mode control offers short minimum on-time, allowing the widest ratio between input and output voltages. Internal loop compensation means that the user is free from the tedious task of calculating the loop compensation components. Fixed 5 V output and adjustable output voltage options are available.
The default switching frequency is set at 500 kHz allowing for small external components and good transient response. In addition, the frequency can be adjusted over a range of 200 kHz to 1 MHz with a single external resistor. The internal oscillator can be synchronized to a system clock or to the oscillator of another regulator. A precision enable input allows simplification of regulator control and system power sequencing. In shutdown mode the regulator draws only 25 µA (typ). An adjustable soft-start feature is provided through the selection of a single external capacitor. The LM22672 also has built in thermal shutdown, and current limiting to protect against accidental overloads.
