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.
A forced continuous mode control pin can ...
