Product Summary
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 μA, a sleep-mode current of less than 100μA 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 applications of the TPS43000PW include Networking Equipment, Servers, Base Stations, Cellular Telephones, Satellite Telephones, GPS Devices, Digital Still and Handheld Cameras, Personal Digital Assistants (PDAs).
