Product Overview

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.
  • High-efficiency buck, boost, SEPIC or flyback (buck-boost) topology
  • Synchronous rectification for high-efficiency
  • Drives external MOSFETs for high-current applications
  • Synchronizable fixed-frequency
  • PWM or automatic pulsed frequency modulation (PFM) mode
  • Built-in soft-start
  • User programmable discontinuous or continuous conduction mode
  • Selectable pulse-by-pulse current limiting or hiccup mode protection
  • Green product and no Sb/Br
