1HS01G,Half-Bridge Resonant Controller,PG-DSO-8

The 1HS01G Half-Bridge Resonant Controller is designed to enhance the efficiency and reliability of LLC resonant half-bridge converters. Packaged in a compact PG-DSO-8 form factor, this IC features a high-accuracy oscillator with a maximum frequency of 600 kHz, making it ideal for high-frequency switching applications. With integrated two-level overcurrent protection, mains undervoltage protection, and adjustable hysteresis, the 1HS01G ensures safe and stable operation. The built-in soft-start feature minimizes inrush current and reduces output voltage overshoot during startup, while the fixed 50% duty cycle operation ensures optimal performance in half-bridge configurations. This IC is perfect for LCD/PDP TVs, AC-DC adapters, and audio SMPS applications.

Designed with efficiency and durability in mind, the 1HS01G includes adjustable blanking time and restart intervals, providing robust protection in fault conditions. Its low component count simplifies circuit design, making it an ideal choice for a wide range of high-performance electronic systems.
