TL3845BD Allgemeine Beschreibung

The TL3845BD is a control integrated circuit that offers a range of features essential for implementing off-line or dc-to-dc fixed-frequency current-mode control applications with minimal external components. It includes internal circuits such as undervoltage lockout (UVLO), a precision reference for accuracy, and logic for latched operation. Moreover, the totem-pole output stage is designed to handle high-peak currents, making it suitable for driving N-channel MOSFETs. The TL3845BD exhibits improved performance compared to previous models, with lower start-up current and optimized oscillator discharge current levels

Hauptmerkmale

Ergonomic Design for Reduced Power Consumption
Safe Operating Area With Undervoltage Lockout
Pulse-Width Modulation (PWM) for Smooth Control
Overcurrent Protection With Hysteresis and Delay
Fault Detection and Automatic Restart
