SD6863
Overview
SD686X is current mode PWM+PFM controller with built-in highvoltage MOSFET used for SWPS, with low standby power and low start current for power switch. In standby mode, the circuit enters burst mode to reduce the standby power dissipation.
- Energy Star 2.0 standard * Lower start-up current (3µA) * Various switching frequency following load for the higher efficiency * Frequency jitter for low EMI * Overvoltage, overcurrent, overload and over temperature protections. * Adjustable limit output power * Undervoltage lockout * Built-in high voltage MOSFET * Auto restart mode * Peak current compensation * Maximum peak current compensation for initialization * Burst mode * Cycle by cycle current limit
