KP3205
KP3205 Fixed 5V output, high-performance low-cost offline PWM controlled power The KP320X is a series of high-performance, low-cost PWM controlled power switches, suitable for offline low-power buck applications, with a simple peripheral circuit and fewer components. At the same time, the product's built-in high-voltage MOSFET enhances the system's surge withstand capability. Unlike traditional PWM controllers, the KP320X does not have a fixed clock-driven MOSFET internally, allowing the system switching frequency to be automatically adjusted with load changes. Meanwhile, the chip adopts multi-mode PWM control technology, effectively simplifying peripheral circuit design, improving line regulation and load regulation, and eliminating audible noise during system operation. In addition, the chip's internal peak current detection threshold can be automatically adjusted according to actual load conditions, effectively reducing standby power consumption under no-load conditions. The KP320X integrates comprehensive protection functions with self-recovery: VDD Under-Voltage Lockout (UVLO), Cycle-by-Cycle Current Limit (OCP), Output Over-Voltage Protection (OVP), FB Abnormal Protection, Over-Load Protection (OLP), and Over-Temperature Protection (OTP).
