Texas Instruments LM5165YDRCT, Synchronous Buck DC-DC Converter, 150mA

The Texas offers a LM series of device which is a compact 3-V to 65-V, ultra-low IQ synchronous buck converter with high efficiency over wide input voltage and load current ranges. With integrated high-side and low-side power MOSFETs, up to 150-mA of output current can be delivered at fixed output voltages of 3.3 V or 5 V.

Wide input voltage range of 3 V to 65 V
Integrated 1-Ω NMOS synchronous rectifier which eliminates external rectifier diode
Programmable current limit set point
