The Texas Instruments TPS62020 evaluation module (EVM) for low-power, high-efficiency, step-down converters helps designers evaluate this device. The EVM enables evaluation of different device modes and device performance.

The TPS64202EVM-023 is an evaluation tool for the TPS64202 inductive step-down controller in SOT-23 package which can supply voltages down to 1.2V from a 1.8-V to 6.5-V input.

The TPS40200EVM-001 evaluation module (EVM) uses the TPS40200 nonsynchronous buck converter to provide a resistor-selected 3.3-V output voltage that delivers up to 2.5 A from a 12-V input bus. The EVM operates from a single supply and uses a single P-channel power FET and Schottky diode to produce a low-cost buck converter. The part operates at a 300-kHz clock frequency with provision for externa…

The Texas Instruments TPS62050 and TPS62052 evaluation modules (EVM) for low-power, high-efficiency, step-down converters help designers evaluate these devices. The EVMs make it possible to evaluate different modes of the devices as well as the device performance.

The controller utilizes a constant on-time control scheme which eliminates the need for external compensation components, allowing the power supply designer to minimize necessary board space and reduce costs.

The TPS40090EVM−001 multi-phase dc-to-dc converter utilizes the TPS40090 multi-phase controller and UCC27222 predictive gate driver to step down a 12-V input to 1.5V @ 100 A at 420 kHz.

The LM2771 is a switched capacitor step-down regulator that produces a 1.5V output without the use of an inductor. It is capable of supplying loads up to 250mA. The LM2771 operates with an input voltage from 2.7V to 5.5V, and requires only 3 low-cost ceramic capacitors.

The TPS5430EVM-173 evaluation module allows the designer to evaluate the TPS5430 SWIFT DC/DC converter and is designed with external components to operate over a wide input voltage range.

Demonstration circuit 1889A features the LTM®4624EY μModule regulator, a tiny high performance high efficiency step-down regulator. The LTM4624EY has an operating input voltage range of 4V to 14V and is able to provide an output current of up to 4A. The output voltage is programmable from 0.6V to 5V.

Many appliances today use non-isolated power supply to furnish low output power required to run a micro, LED display, and a few relays or AC switches. This type of power supply has a single rectifier so as to reference the neutral to output ground in order to fire TRIACs or AC switches.
