LTC3114IDHC-1#PBF

The LTC3114IDHC-1#PBF is a high-efficiency switching DC-DC regulator from Analog Devices (Linear Technology). It’s a multi-output (quad/synchronous) buck regulator family designed to generate low-voltage rails from a higher input, with integrated MOSFETs and a control loop suitable for dense, power-critical applications.
Key points:
- Integrates power switches and control circuitry for efficient step-down conversion.
- Suitable for multi-rail power supplies in processors, FPGAs, GPUs, and other digital systems.
- Features typically include current-mode control, programmable switching frequency, enable/disable, overcurrent protection, and thermal shutdown.
- Package: IDHC (lead-free, RoHS-compliant) with the -PBF suffix indicating a lead-free variant; -1 denotes a specific fixed/adjustable output variant.
Why useful: simplifies designs by combining several functions in one device, reducing board size and component count, while enabling tight regulation and protection.
For exact specs (input range, output voltages, switching frequency, pinout, and application diagrams), refer to the LTC3114 datasheet and the Analog Devices product page.

Here are the key features of LTC3114IDHC-1#PBF (data-sheet style):
- Wide input voltage range: supports 4V to 38V
- Buck-Boost operation with two external N-channel MOSFETs for power stage
- Synchronous rectification (no external diodes required) for high efficiency
- High output current capability (up to several amperes, depending on external FETs)
- External clock synchronization (SYNC) for fixed or synchronized operation
- Current-mode control with programmable current limit
- Soft-start to reduce inrush and enable clean startup
- Enable/shutdown control and Power-Good/status indication
- Protections: UVLO, Overvoltage (OVP), Overcurrent/short-circuit with protection, and thermal shutdown
- Suitable for wide Vin-to-Vout regulation in buck, boost or buck-boost modes
- Packaging: 28-pin HTSSOP/IDHC family, lead-free (PBF), RoHS compliant
Notes:
- Requires external MOSFETs for the power stage.
- Typical switching frequency and exact current rating depend on external components and application.

8-pin DFN package (3×3 mm) with exposed pad, Pb-free.

- Pin count: 28 pins
- Function: A high-efficiency buck-boost DC-DC regulator controller with integrated MOSFETs (synchronous buck-boost). It regulates voltage over a wide input range, using current-mode control to perform buck, boost (and buck-boost) conversions.

Manufacturer: Analog Devices, Inc. (ADI). It is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing (DSP) integrated circuits; the LTC line originated from Linear Technology, now part of Analog Devices.
