Description

PMP7758 is a non-synchronous buck DC-DC controller with 6-20V DC input and 3.3V @ 1A output. It is a low cost, efficient switching regulator. It uses LM25011 which contains an N channel buck switch, a startup regulator, current limit detection, and internal ripple control. The constant on-time regulation principle requires no loop compensation, results in fast load transient response, and simplifies circuit implementation.
