Key Features
- Dual synchronous step-down outputs each delivering up to 6 A from a 3.1 V to 20 V input range (VIN2 supports 1.5 V to 20 V), enabling flexible multi-rail power architecture in a single IC
- Phase-shift current-mode control with 0.6 V to 5 V adjustable output per channel provides fast transient response and tight regulation for FPGA core and I/O rail designs
- 28-pin QFN EP package with exposed thermal pad minimizes PCB footprint while enabling efficient heat dissipation for dual 6 A channel operation in high-density power modules
Applications
The LTC3636EUFD#TRPBF is designed for dual-rail point-of-load power conversion in FPGAs, ASICs, and multi-core processors requiring simultaneous 6 A regulation on two independent voltage rails from a 12 V bus. Its 3.1 V to 20 V input flexibility and 0.6 V to 5 V output range also suit industrial embedded computing, telecom line cards, and network equipment where multiple sub-5 V rails must be generated efficiently from a common intermediate bus voltage.

Frequently Asked Questions
What input voltage range and output current capability does LTC3636EUFD#TRPBF support per channel?
The LTC3636EUFD#TRPBF accepts 3.1 V to 20 V on VIN1 (or 1.5 V to 20 V on VIN2) and delivers up to 6 A per channel with adjustable output voltage from 0.6 V to 5 V, making it suitable for dual-rail FPGA and processor core power designs converting from a standard 12 V intermediate bus.
How does phase-shift current-mode control in LTC3636EUFD#TRPBF benefit FPGA power rail design?
Phase-shift current-mode control interleaves the two 6 A switching channels 180° out of phase, effectively doubling the output ripple frequency and halving input capacitor ripple current, which reduces input and output filter capacitor size by up to 50% and improves load transient response with sub-100 µs recovery times on FPGA core voltage rails.
What makes the 28-pin QFN EP package of LTC3636EUFD#TRPBF suitable for high-density power designs?
The 28-pin QFN package with exposed thermal pad (EP) occupies a compact PCB footprint of approximately 4 × 5 mm while providing low thermal resistance from junction to board, allowing the dual 6 A controller to dissipate heat efficiently through the PCB copper pour without requiring an external heatsink in most operating scenarios below 85°C ambient.
When would LTC3636EUFD#TRPBF be selected over a single-output DC-DC controller in a system design?
LTC3636EUFD#TRPBF is preferred over two separate single-output controllers when a design requires two independently regulated rails from 0.6 V to 5 V at up to 6 A each, because the phase-shifted dual-channel architecture saves PCB area, reduces BOM count by approximately 30%, and provides inherent input capacitor ripple cancellation for tighter power integrity on FPGA and processor multi-rail applications.
