KP3501A
KP3501A High-performance, low-cost offline PWM control switch The KP3501A is a non-isolated, highly integrated, and low-cost PWM power switch suitable for buck and boost circuits. The KP3501A uses a high-voltage single-wafer process, integrating a 500V high-voltage MOSFET and a controller using switch-mode peak current mode control on the same wafer. It ensures a high-precision 5V default output across the full voltage input range. Internally, the minimum Toff time is fixed at 20μs and includes a frequency dithering function, optimizing EMI effects while ensuring output power. The chip also features light and heavy load modes, easily achieving standby power consumption below 50mW. The KP3501A integrates comprehensive protection functions: VDD undervoltage protection, cycle-by-cycle current limiting, abnormal overcurrent protection, overtemperature protection, overload protection, and short-circuit protection.
