Product Description

The NCP1077STAT3G is a High-voltage Switcher with 65kHz frequency for low power offline Switched Mode Power Supply (SMPS). It integrates fixed frequency current mode controller with a 700V MOSFET. It offers a high level of integration, including soft-start, frequency-jittering, short-circuit protection, skip-cycle, a maximum peak current set point, ramp compensation and a dynamic self-supply. When the output power demand diminishes, the IC automatically enters frequency fold-back mode and provides excellent efficiency at light loads. When the power demand reduces further, it enters into a skip mode to reduce the standby consumption down to a no load condition. Protection features includes a timer to detect an overload or a short-circuit event, overvoltage protection with auto-recovery and AC input line voltage detection. For improved standby performance, the connection of an auxiliary winding stops the DSS operation and helps to reduce input power consumption below 50mW at high line.
Large creepage distance between high-voltage pins
Skip-cycle operation at low peak currents only - No acoustic noise
Dynamic self-supply - No need for an auxiliary winding
Auto-recovery output short circuit protection with timer-based detection
Auto-recovery overvoltage protection with auxiliary winding operation
Frequency jittering for better EMI signature, including frequency foldback mode
Frequency fold-back to improve efficiency at light load
Internal temperature shutdown
Internal 1ms soft-start
<50mW No load input consumption
