Texas Instruments' LMR22007 is a switching regulator designed for the high-efficiency requirement of applications with stand-by and shut-down modes. The device features a low-current mode to maintain efficiency under light-load conditions, and an adaptive on-time control architecture for fast transient response.
The LMR22007 can deliver up to 750 mA of continuous load current with an adjustable input current limit. The device has a wide input voltage range of 2.7 to 20 V, and supports VIN
transients to 24 V. Other features include internal compensation, internal soft start, input under-voltage protection, internal bootstrap diode, and thermal shutdown.
