LTC1625 No RSENSETM Current Mode Synchronous Step-Down Switching Regulator FEATURES s s s s s s s s s s s s s s s s DESCRIPTION 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 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.
