Description
The HT7A3942 is a high performance, low cost Current Mode PWM controller for
providing necessary feature to implement Off-Line application. By Optimizing
for the Energy Star 2.0 spec., the Power Supply Unit (PSU) implemented using
the HT7A3942 can satisfy the “Energy Star No-Load Mode” Stand-by Power
standard, which is less than 0.3W within all Nameplate Output Power Range of
0~250W. Internally implemented circuits include a trimmed Oscillator for
precise frequency control, a temperature-compensated Voltage Reference, Slope
Compensation, Leading-Edge Blanking, and a patented Non-Audible Noise Green
Mode Control Scheme.
The HT7A3942 features a range of various protection functions such Short-
Circuit Protection (SCP, which can also be used for Over-Load Protection,
OLP), Cycle-by-Cycle Current Limiting and Under Voltage Lock-Out (UVLO).
