Introduction

AI Translation

SP6601A is a current-mode PWM controller. It operates at a fixed frequency in PWM mode, which is precisely set internally. Under no-load or light-load conditions, the operating frequency is adjusted internally by the IC. The chip can operate in green mode to reduce light-load losses and improve overall efficiency. It requires only a small startup and operating current, allowing a high-value resistor to be used in the startup circuit to further reduce standby power consumption. The chip features a built-in slope compensation circuit that prevents sub-harmonic oscillation and improves system stability when operating at high duty cycles. A built-in leading-edge blanking time eliminates the effect of diode reverse recovery current in the snubber network. Frequency dithering technology is employed to effectively improve the system's EMI performance. The frequency hopping threshold is set above the audio range (20KHz) to avoid audible noise during operation. Multiple built-in protections are included: cycle-by-cycle current limiting (OCP), overload protection (OLP), overvoltage protection (OVP), VDD overvoltage clamping, undervoltage lockout (UVLO), and overtemperature protection (OTP). The internal totem-pole driver structure further improves the system's EMI characteristics and provides soft-start control for the switching device.
