Overview

The TPS43000PW is a high-frequency, voltage-mode, synchronous PWM controller that can be used in buck, boost, SEPIC, or flyback topologies. This highly flexible, full-featured controller is designed to drive a pair of external MOSFETs (one N-channel and one P-channel), enabling it for use with a wide range of output voltages and power levels. With an automatic PFM mode, a shutdown current of less than 1 uA, a sleep-mode current of less than 100 uA and a full operating current of less than 2 mA at 1 MHz, it is ideal for building highly efficient, dc-to-dc converters.

The TPS43000 features a selectable two-level current-limit circuit which senses the voltage drop across the energizing MOSFET. The user can select either pulse-by-pulse current limiting or hiccup mode overcurrent protection. The TPS43000 also features a low-power (LP) mode (which reduces gate charge losses in the N-channel MOSFET at high input/output voltages), undervoltage lockout, and soft-start. The TPS43000 is available in a 16-pin TSSOP (PW) package.
