L6726A is a single-phase step-down controller with integrated high-current drivers that provides complete control logic, protections and reference voltage to realize in an easy and simple way general DC-DC converters by using a compact SO-8 package.
The L6726A is a single-phase step-down controller designed for general DC/DC converters, subsystem power supplies, and memory termination supplies. It features a flexible power supply range from 5 V to 12 V and can handle power conversion inputs as low as 1.5 V. The device includes an internally fixed 270 kHz oscillator, programmable soft-start, and integrated high-current drivers for HS and LS MOSFETs.
