TS3843B - High Performance Current Mode Controller

Download the TS3843B datasheet PDF. This datasheet also covers the TS3842B variant, as both devices belong to the same high performance current mode controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The TS3842B and TS3843B series are high performance fixed frequency current mode controllers.

This is specifically designed for Off-Line and DC-to-DC converter applications offering the designer a cost effective solution with minimal external components.

Key Features

  • consisting of input and reference undervoltage lockouts each with hysteresis, cycle-by-cycle current limiting, programmable output deadtime, and a latch for single pulse metering. This device is available in 8-pin dual-in-line plastic packages as well as the 8-pin plastic surface mount (SOP-8). The SOP-8 package has separate power and ground pins for the totem pole output stage. The TS3842B has UVLO thresholds of 16V (on) and 10V (off), ideally suited for off-line converters. Features Trimmed O.
