NCP1077STBT3G Description

Short technical summary and product information.

The ON Semiconductor NCP1077STBT3G is a high-voltage switcher designed for low power offline Switched-Mode Power Supplies (SMPS). This integrated circuit features a built-in 700V MOSFET with a peak current capability of 800 mA for the NCP1077 series. It operates in current-mode fixed frequency mode at 100 kHz, with options for 65 kHz and 130 kHz available in the NCP107x family.

 

The NCP1077STBT3G offers a high level of integration, including features like soft-start, frequency jittering for improved EMI, skip-cycle operation for reduced acoustic noise, and Dynamic Self-Supply which eliminates the need for an auxiliary winding. Protection features include auto-recovery output short circuit protection with timer-based detection and auto-recovery overvoltage protection.

 

This device is available in a SOT-223 (TO-261) surface mount package, suitable for applications requiring compact designs. The operating temperature range is -40°C to 125°C (TJ). Its topology is Flyback, and it supports isolated output configurations.

 

Key specifications include a duty cycle of 69%, fault protection against overload, over temperature, over voltage, and short circuit conditions. The device has an internal switch and operates within a voltage range of 6.3V to 10V.
