BH0170A - FSBH0170A

Description

The highl y i ntegrated F SBH-series c onsists of an integrated curr ent-mode Puls e W idth Mod ulator (PW M) and an av alanche-rugged 700V S enseFET.

It is specifically designed for high-p erformance offlin e Switched-Mode Po wer Su pplies (SMPS) with minimal external components.

Features

  • Brownout Protection with Hysteresis Built-In 5ms Soft-Start Function Internal Avalanche-Rugged 700V SenseFET Low Acoustic Noise During Light-Load Operation High-Voltage Startup Linearly Decreasing PWM Frequency to 18KHz Peak-Current-Mode Control Cycle-by-Cycle Current Limiting Leading-Edge Blanking (LEB) Synchronized Slope Compensation Internal Open-Loop Protection VDD Under-Voltage Lockout (UVL.
