GreenChip SMPS Control IC

Features

SMPS controller IC for low-cost applications
Large supply voltage range (up to 30 V)
Integrated high-voltage start-up
Continuous VCC regulation during start-up and protection via the HV pin, allowing a minimum VCC capacitor value
Reduced opto current in burst mode enabling low no-load power consumption
Operating frequencies in all operating modes are outside the audible area
Integrated X-capacitor discharge
Adjustable soft start
Low supply current during normal operation (0.6 mA without load)
Low supply current during non-switching state in burst mode (0.2 mA)
Valley switching for minimum switching losses
Frequency reduction with fixed minimum peak current to maintain high efficiency at low output power levels
Mains voltage independent OverPower Protection (OPP)
OverTemperature Protection (OTP)
Integrated overpower time-out
Continuous mode protection using demagnetization detection
Accurate OverVoltage Protection (OVP)
