LTC1625 - Linear Technology

LTC1625 Current Mode Synchronous Step-Down Switching Regulator

The LTC®1625 is a synchronous step-down switching regulator controller that drives external N-Channel power MOSFETs using few external components. Current mode control with MOSFET VDS sensing eliminates the need for a sense resistor and improves efficiency. The frequency of a nominal 150kHz internal oscillator can be synchronized to an external clock over a .

Current mode control with MOSFET VDS sensing eliminates the need for a sense resistor and improves efficiency. The frequency of a nominal 150kHz internal oscillator can be synchronized to an external clock over a 1.5:1 frequency range. Burst ModeTM operation at low load currents reduces switching losses and low dropout operation extends operating time in battery-powered systems. A forced continuous mode c.
