KP35026

KP35026VG is a high performance Switch Mode Power Supply Switcher for 3.3V low power off-line application with minimum components in typical buck solution. This IC has built-in high break down voltage MOSFET to withstand high surge input.

Unlike conventional PWM control, there’s no fixed internal clock in KP35026VG to trigger the GATE driver, the switching frequency is changed according to the load condition. The multi-mode PWM control and fast dynamic response circuit are integrated to achieve high dynamic response and good line/load regulation without audio noise generated. The peak current limit changes according to the real load condition for low standby power in no load.

KP35026VG integrates functions and protections of Under Voltage Lockout (UVLO), Output Over Voltage Protection, Cycle-by-cycle Current Limiting (OCP), On-chip Thermal Shutdown, Over Load Protection (OLP) with Auto Recovery Mode Protection, etc.
