LTC3808 - No RSENSE, Low EMI, Synchronous DC/DC Controller With Output Tracking

The LTC3808 is a synchronous Step-down Switching Regulator controller that drives external complementary Power MOSFETs using few external components. The constant frequency current mode architecture with MOSFET VDS sensing eliminates the need for a Current Sense resistor and improves efficiency.
Burst Mode operation provides high efficiency operation at light loads. 100% duty cycle provides low dropout operation, extending operating time in battery-powered systems.
The switching frequency CAN be programmed up to 750kHz, allowing the use of small surface mount inductors and capacitors. For noise sensitive applications, the LTC3808 CAN be externally synchronized from 250kHz to 750kHz. Burst Mode is inhibited during synchronization or when the SYNC/MODE pin is pulled low to reduce noise and RF interference. To further reduce EMI the LTC3808 incorporates a novel spread spectrum frequency modulation technique.
The LTC3808 is available in the tiny footprint thermally enhanced DFN package or 16-lead SSOP package.
