TL2843BDR-8 TI DC DC Switching Controllers

The TL2843B is a current-mode PWM controller operating from 7.6V to 30V, featuring 1A totem-pole output for driving power MOSFETs. It includes a trimmed oscillator with 52kHz typical frequency and low start-up current of 0.5mA maximum. The device provides UVLO with 8.4V on threshold and 7.6V off hysteresis. Cycle-by-cycle current limiting and thermal protection ensure robust operation. The TL2843B is optimized for off-line and DC-DC converters with low start-up current. Selection is ideal for low-cost flyback and forward converters. Applications include AC-DC adapters, battery chargers, isolated telecom power supplies, and industrial power converters requiring current-mode control with low start-up current.
