Visão Geral
Description
- Function: It drives two external MOSFET pairs to build high‑current voltage rails (VRMs). It does not include power MOSFETs.
- Operation: Two PWM/current‑mode channels with phase sharing for multi‑phase regulation; programmable switching frequency and protection features.
- Packaging/ordering: The EGN suffix denotes the device package; #TRPBF means Tape‑And‑Reel Pb‑Free packaging.
- Typical use: CPU/GPU core voltage regulators, multi‑phase power supplies in telecom and other high‑current applications.
- What you need: external power MOSFETs, inductors, sense resistors, and feedback components; reference designs and the datasheet provide exact pinout and operating ranges.
For exact electrical specs and pinout, consult the LTC3850 datasheet on Analog Devices’ website.
Features
- Dual, interleaved synchronous buck DC-DC controller
- Wide input voltage range (suitable for automotive/industrial applications)
- Current-mode PWM control with cycle-by-cycle current limiting
- Programmable switching frequency
- Soft-start and voltage tracking for each channel
- Independent feedback for dual outputs
- Protections: overcurrent/short-circuit, overvoltage, thermal shutdown
- Undervoltage lockout and an enable control
- Power-good/diagnostic status output
- Integrated control logic optimized for multi-phase, high-current supplies
- 28-pin EGN package with Tape & Reel (TRPBF) packaging
Note: This summary provides typical features for LTC3850-series controllers; always refer to the product data sheet for exact specifications and pinout.
Pinout
