Overview

SC1117DG incorporates a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC. The startup and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry. SC1117DG combines a high-voltage power MOSFET switch with a power supply controller in one device. Unlike conventional PWM (pulse width modulator) controllers, a simple ON/OFF control regulates the output voltage. The controller consists of an oscillator, feedback (sense and logic) circuit, 5.8 V regulator, BYPASS pin undervoltage circuit, over-temperature protection, frequency jittering, current limit circuit, and leading edge blanking integrated with a 700 V power MOSFET. The SC1117DG incorporates additional circuitry for auto-restart.

Applications

Supplies for appliances, industrial systems, and metering

Key features

Fully integrated auto-restart for short circuit and open-loop protection
Frequency jittering greatly reduces EMI
Meets HV creepage requirements between DRAIN and all other pins both on the PCB and at the package
Lowest component count switcher solution
Accurate hysteretic thermal shutdown protection – automatic recovery improves field reliability
Universal input range allows worldwide operation
Simple ON/OFF control, no loop compensation needed
Very low component count – higher reliability and single side printed circuit board
Auto-restart reduces delivered power by 95% during short circuit and open-loop fault conditions
High bandwidth provides fast turn-on with no overshoot and excellent transient load response
Ideal for Buck/Buck-Boost configuration
Simplified feedback in non-isolated flyback configuration
Easily meets all global energy efficiency regulations with no added components
No-load consumption < 300 mW without bias winding at 265 VAC input (< 30 mW with bias winding)
ON/OFF control provides constant efficiency to very light loads – ideal for mandatory CEC regulations
