Frequently Asked Questions
What input voltage range and output current capability does the LTC3636EUFD#PBF support across both channels?
The LTC3636EUFD#PBF operates from a 3.1 V to 20 V primary input, with the second channel accepting VIN2 as low as 1.5 V, and delivers up to 6 A per channel with output voltages adjustable from 0.6 V to 5 V. This enables powering dual FPGA core and I/O rails simultaneously from a single 12 V backplane supply.
How does the phase-shift control of the LTC3636EUFD#PBF benefit PCB designs with tight EMI budgets?
Phase-shift control offsets the switching cycles of the 2 output channels by 180 degrees, reducing peak input current ripple by up to 50% compared to in-phase dual-channel regulators. This allows designers to use smaller input bulk capacitors, often reducing required input capacitance from 100 µF to 47 µF, and eases EMI compliance for FCC and CISPR 22 Class B standards.
When is LTC3636EUFD#PBF a better choice than using two discrete single-channel regulators for a dual-output 12 V system?
The LTC3636EUFD#PBF integrates 2 synchronous 6 A buck regulators with shared phase-shift timing in a single QFN package, reducing PCB footprint by approximately 30% versus two separate controllers plus external MOSFETs. It also guarantees matched timing between channels for optimal ripple cancellation, which discrete designs require additional circuitry to achieve, lowering both BOM cost and design complexity.
