Descripción general

Description

LT8636HV#PBF is the high‑voltage version of Linear Technology/Analog Devices’ LT8636 family—a wide‑input buck‑boost DC‑DC regulator controller. It can regulate an output that is higher or lower than the input using one external inductor and external MOSFETs (buck‑boost topology). It uses current‑mode control with a fixed switching frequency, provides soft‑start, and includes protections such as UVLO, overvoltage, overcurrent, and thermal shutdown. It requires an external MOSFET pair, inductor, and feedback network to set the output. The #PBF suffix denotes the package type (PBF). Typical applications include automotive, industrial, solar, and battery-powered systems requiring a stable regulator from a variable/high input voltage.

Features

Here are the key features of LT8636HV#PBF (high‑voltage, synchronous buck regulator):
- High input voltage range suitable for automotive/industrial (HV).
- Integrated high‑side and low‑side MOSFETs for a synchronous buck.
- Current‑mode PWM control for efficient regulation.
- Adjustable output voltage via feedback resistors.
- Enable/disable input with undervoltage lockout.
- Soft‑start to limit inrush at power‑up.
- Power‑good/status flag (PGOOD).
- Robust protections: cycle‑by‑cycle current limit, overcurrent/short‑circuit protection, overvoltage protection, thermal shutdown.
- Wide operating temperature range for harsh environments.
- PbF packaging option (PBF variant) for compact assemblies.
Designed for reliable operation in challenging power‑conversion applications, with protections and status signaling to simplify design.

Package

Plastic Pb-free QFN package (surface-mount) for LT8636HV#PBF.

Pinout

Pin count: 28 pins (Pb-free, PBF) in a 28-pin QFN package.
Function: LT8636HV#PBF is a high-voltage dual synchronous buck regulator controller. It accepts input up to about 60V and provides two switching regulators via LX1 and LX2. Each channel has its own feedback (FB1, FB2), compensation (COMP1, COMP2), and current sense for precise regulation. Additional functions include EN (enable), TRACK/SS (soft-start/tracking), PGOOD (power-good), OSC/SYNC (frequency or synchronization), and protection features such as UVLO, OVP, and OC. It is intended for dual-output power-supply designs with a shared input but independent outputs.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI). The LT8636HV was originally from Linear Technology (the LT prefix); Linear Technology is now part of Analog Devices (acquired in 2017).
- Company type: A global American semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits (ICs) for a wide range of applications.

Application

LT8636HV#PBF is a high‑voltage, wide‑input DC‑DC converter. Typical applications:
- Automotive power electronics (12/24V systems, transient/load-dump protection)
- Industrial and motor‑drive front ends
- Solar/battery backup and energy‑storage systems
- Non‑isolated buck/boost supplies for telecom and servers
- Portable/battery‑powered equipment needing wide input range and high efficiency
