RT6575K
RT6575K is High Efficiency Single Synchronous DC-DC Step-Down Controller manufactured by Richtek.
High Efficiency Single Synchronous DC-DC Step-Down Controller with 5V LDO
General Description
RT6575K is a single-channel step-down controller generating supply voltage for battery-powered systems. It includes a Pulse-Width Modulation (PWM) controller adjustable from 2V to 5.5V, and a fixed 5V linear regulator. The linear regulator provides up to 100mA output current. Other Features include on-board powerup sequencing, a power-good output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown.
A constant current ripple PWM control scheme operates without sense resistors and provides 100ns response to load transient. For maximizing power...
