Product Overview

The LTM4609MPV#PBF is a high efficiency switching mode buck-boost power supply DC/DC µModule Regulator includes the switching controller, power FETs and support components. Operating over an input voltage range of 4.5 to 36V, it supports an output voltage range of 0.8 to 34V, set by a resistor. This high efficiency design delivers up to 4A continuous current in boost mode. Only the inductor, sense resistor, bulk input and output capacitors are needed to finish the design. The high switching frequency and current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. It can be frequency synchronized with an external clock to reduce undesirable frequency harmonics. Fault protection features include overvoltage and fold-back current protection.
  • Single inductor architecture allows VIN above, below or equal to VOUT
  • Current mode control
  • Power good output signal
  • Ultrafast transient response
  • Current foldback protection
  • Output overvoltage protection
  • Up to 98% efficiency
  • 200 to 400kHz Phase-lockable fixed frequency
