Visão Geral
Description
Key features (typical): dual synchronous buck outputs with current‑mode control, soft‑start, enable/shutdown, overcurrent protection, thermal shutdown, PGOOD, and adjustable output voltages via external feedback resistors. It’s suited for power rails in FPGAs/GPUs, ASICs, DSPs, microprocessors, and telecom/industrial systems where multiple rails are required from a single supply.
For exact specs (input range, max current per rail, switching frequency, layout recommendations, and package dimensions), consult the LTC3630A datasheet and the -TRPBF package note.
Features
- Wide input voltage range (high voltage capable)
- Integrated high-side and low-side MOSFETs (synchronous operation)
- Buck regulator architecture with external feedback for output regulation
- High efficiency
- Constant-frequency, current-mode control
- Programmable switching frequency
- Soft-start to limit inrush and output overshoot
- Protection: cycle‑by‑cycle current limit, overcurrent/short-circuit protection, overtemperature protection, undervoltage lockout (UVLO)
- Enable input for power sequencing
- Small 16‑lead MSOP package (AIDHC), RoHS compliant, Tape & Reel (TRPBF)
Note: for exact voltage ranges, current capability, and pinouts, please consult the latest datasheet.
Pinout
- Function: Dual synchronous buck regulator/controller. It provides two independent PWM-controlled buck converter channels with integrated high- and low-side MOSFETs, external feedback/compensation, enable, soft-start, current limit, protections, and power-good signals. Suitable for high-efficiency DC-DC conversion from a higher input to two regulated outputs.

Application
- Battery-powered/portable devices: efficient buck-boost regulation for Li‑ion packs and rugged power rails.
- Solar energy/storage and microgrids: interface between PV/battery and system loads with high efficiency.
- Telecom and industrial DC-DC supplies: robust, high-efficiency regulators over wide input ranges.
- Post-regulation/VRMs: voltage regulation for CPUs/GPUs/ASICs requiring multiple rails from a common source.
