资 源 简 介
The TPS43000 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 operates over a wide input voltage range of 1.8 V to 9.0 V. Typical power sources are distributed power systems, two to four nickel or alkaline batteries, or one to two lithium-ion cells.
