Description

The TPS43000PW is a synchronous PWM Controller 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 1uA, a sleep-mode current of less than 100uA and a full operating current of less than 2mA at 1MHz, it is ideal for building highly efficient, DC to DC converters. This high-frequency voltage-mode controller operates over a wide input voltage range of 1.8 to 9V. Typical power sources are distributed power systems, two to four nickel or alkaline batteries, or one to two lithium-ion cells. It can be used to generate regulated output voltages from as low as 0.8 to 8V or higher. It operates either in a fixed-frequency mode, where the user programs the frequency (up to 2MHz), or in an automatic PFM mode.
