Products Detail

The RT8458A is a PWM buck LED driver controller with integrated high-side gate driver for step-down converters. It regulates constant output current by controlling external MOSFETs, supporting up to 100% duty cycle for wide input voltage applications like E27 and PAR30 offline LED lighting. Features include a 47kHz fixed-frequency oscillator, internal -220mV precision reference, PWM comparator with latching logic, and averaging current feedback loop for accurate LED current. The device offers multiple protections: UVLO, OCP, OVP, thermal shutdown, and LED string open/short/over-current protection. Dimming control is implemented via ACTL pin. Housed in TSOT-23-6 package for compact design.
