Smallest regulator delivers 94.6% eff in 30-mm2 footprint

The LMR22007 is the industry’s smallest 12-V, 750-mA dc/dc power regulator. It integrates a synchronous MOSFET that delivers peak efficiency of 94.6%. The switching regulator provides a complete 12-V, Vin to Vout power supply design that measures 2 with as few as three external components. The device targets space-constrained and power dense applications in a variety of markets, including consumer, industrial and automotive.

The nano regulator operates from 2.7 to 20 V input and delivers an output voltage from 0.9  to 5.5 V and survives Vin transients to 24 V. Applications include single to multiple Li-ion cells, USB, 5-Vin and 12-Vin power supplies. The operating temperature of the device extends from -40° to +125°C. Other features include internal compensation, internal soft start, input under-voltage protection, internal bootstrap capacitor and thermal shutdown.
