LTC7804 Datasheet Boost Controller

Manufacturer: Analog Devices

Overview: LTC7804 Low IQ Synchronous Boost Controller with Spread Spectrum.

Datasheet Details

The LTC®7804 is a high performance synchronous boost DC/DC switching regulator controller that drives an all N-channel power MOSFET stage.

Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements.

A constant frequency current mode architecture allows a phase-lockable switching frequency of up to 3MHz.

n Synchronous Operation for Highest Efficiency and Reduced Heat Dissipation n Wide VIN Range: 4.5V to 40V and Operates Down to 1V After Start-Up n Output Voltage Up to 40V n Low Operating IQ: 14μA n Spread Spectrum Operation n Pass-Thru™/100% Duty Cycle Capability for Synchronous MOSFET n RSENSE or Inductor DCR Current Sensing n Programmable Fixed Frequency (100kHz to 3MHz) n Phase-Lockable Frequency (100kHz to 3MHz) n Selectable Continuous, Pulse-Skipping, or Low Ripple Burst Mode® Operation at.
