RT9214PS General Description

Richtek Technology's RT9214PS is a cutting-edge synchronous buck converter IC that sets the standard for efficiency and performance in power management applications. Its wide input voltage range of 4.5V to 18V and adjustable output voltage from 0.8V to 12V make it a versatile choice for a wide range of applications. The integrated high-side and low-side MOSFETs reduce external component count and simplify design, while the fixed switching frequency of 500kHz strikes a perfect balance between efficiency and component size. With its synchronous rectification architecture and pulse-width modulation (PWM) control scheme with voltage mode feedback, the RT9214PS ensures stable output regulation and transient response, delivering reliable performance in demanding operating conditions
