概述

Description

CAT3636HV3-T2 is a high‑voltage LED driver IC (constant‑current DC‑DC controller) in the CAT3636HV3 family. It integrates a switching MOSFET and control logic to regulate LED current from a wide input voltage, suitable for automotive and industrial lighting.
Key features (typical):
- Wide input range (high‑voltage, automotive‑style)
- Constant‑current LED regulation with sense resistor
- PWM/dimming input for brightness control
- Soft‑start and programmable switching frequency
- Protections: overcurrent, overvoltage, thermal shutdown, fault protection
- Compact package options for OEM designs
Typical applications:
- Automotive interior/exterior lighting, backlighting, signage, and LED string drives
What you’ll design:
- VIN, inductor, diode, output capacitor per datasheet
- LED current set via sense resistor
- DIM/EN signal for dimming control
For precise electrical specs, recommended operating ranges, and reference designs, consult the CAT3636HV3-T2 datasheet and manufacturer application notes.

Package

Leadless QFN (DFN) package, typically 32‑pin, 4×4 mm (T2 variant).

Pinout

Pin count: 8 pins (T2 package).
Function: High-voltage DC-DC buck regulator with an integrated switch (used to convert a higher input voltage to a lower regulated output). Includes typical control/diagnostic pins such as enable and feedback; exact pin names/layout depend on the T2 package variant. For precise pinout, refer to the CAT3636HV3-T2 datasheet.

Manufacturer

Manufacturer: Catalyst Semiconductor (the “CAT” prefix).
Company type: A fabless semiconductor company that designs analog/mixed-signal and power-management ICs; it was acquired by ON Semiconductor and is now part of ON Semiconductor.

Application

Applications include:
- Automotive lighting and dashboards
- LED signage and backlighting
- DC-DC conversion and overall power-management in consumer electronics
- Battery-powered devices
- Industrial control and actuator drivers
