    Products Detail

    The RT8128A/C is a synchronous buck PWM controller featuring Richtek Mach ResponseTM technology for 100ns instant-on response to load transients. It eliminates current sense resistors for cost reduction and drives large synchronous rectifier MOSFETs. Supports input voltage ranges: VCC 4.5V-13.2V, power stage 2.5V-24V. Output voltage range: 0.6V-5V. Key features include fixed 300kHz operation, diode emulation mode (RT8128A), VIN detection, pinless LGATE over-current setting, power good indication, embedded bootstrap switch, low-side current sensing, 1% accurate 0.6V reference, enable function, and comprehensive protection (OVP/UVP/OTP/Pre-OVP/OCP). RoHS compliant and halogen-free.
