Overview
The RT9214PSP is a high-efficiency synchronous buck PWM DC-DC controller manufactured by Richtek USA Inc. Designed for generating logic-supply voltages in PC-based systems, it operates with 5V or 12V supply voltages and drives low-cost N-channel MOSFETs. The device features a fixed 300kHz oscillator, internal soft-start, and adaptive non-overlapping gate driver. It includes over-current fault monitoring on the MOSFET without requiring a current sense resistor. The component is housed in an SOP-8 package with an exposed pad.
Feature Summary
- Voltage Mode PWM Control
- Internal Soft-Start
- Over-Current Fault Monitor
Applications
- Graphic Card
- Motherboard, Desktop Servers
- IA Equipments
- Telecomm Equipments
- High Power DC/DC Regulators
Procurement Notes
