The RT8299ZSP is a single-chip, current-mode pulse-width modulator (PWM) controller from Richtek. It is designed to provide high efficient, low noise, and adjustable output voltage regulation solutions for AC/DC adapters, PLC power solutions, and POL converters. This controller offers additional features such as variable soft-start, voltage/frequency tracking, standby control, current limit, and pulse-skip, allowing users to design highly efficient and reliable switching solutions. The RT8299ZSP is supported by an integrated high precision voltage reference and error amplifier which provides an output voltage range of 0.8V to 5.25V; this allows greater design flexibility. It is packaged in an 8-pin SOP-8, making it ideal for height restricted applications.
