Richtek RT8230AGQW

降压同步（2），线性（LDO）（2）4控制器5V ~ 25V

Overview

The RT8230AGQW is a dual-channel Synchronous Step-down Controller generating supply voltages for battery-powered systems. It includes two Pulse-Width Modulation (PWM) controllers adjustable from 2 to 5.5V and two fixed 5/3.3V linear regulators. Each linear regulator provides up to 100mA output current. The 5V linear regulator supplies power to the PWM drivers. The RT8230AGQW includes on-board power-up 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. To eliminate noise in audio applications, an ultrasonic mode is included, which maintains the switching frequency above 25kHz. Moreover, the diode-emulation mode maximizes efficiency for light load applications.
