概述

Description

UCC5880QDFCRQ1 is a Texas Instruments high‑voltage PWM controller for switch‑mode power supplies. It provides current‑mode regulation for driving an external power switch in isolated or nonisolated topologies (e.g., flyback, buck, boost). Key features typically include a wide input voltage range, adjustable oscillator frequency, soft‑start, and an enable input, along with protections such as undervoltage lockout, overcurrent/short‑circuit protection, overvoltage protection, and thermal shutdown. The device is intended for compact, efficient SMPS designs and handles duty‑cycle modulation and protection logic, reducing external component count. The QDFCRQ1 suffix denotes TI’s packaging (RoHS‑compliant QFN with specific tape & reel options). For exact electrical specifications (input range, startup current, switching frequency, current limit, etc.), consult the official UCC5880 datasheet and product page.

Features

Here are the typical features of TI UCC5880QDFCRQ1 (automotive-grade, flyback controller):
- Automotive-qualified (AEC-Q100) device
- Wide input voltage range for off-line Universal input
- High-performance PWM controller with current-mode control
- Valley-switching/low switching losses for improved efficiency
- Green/eco-mode or light-load efficiency optimization
- Built-in high-voltage startup and bias regulator
- Hiccup or cycle-by-cycle overcurrent protection
- Overvoltage/short-circuit protection and UVLO
- Thermal shutdown and soft-start for stability
- Enable/disable/shutdown control pin
- Small QFN package (RoHS compliant) suitable for compact power supplies
Note: Please consult the official TI datasheet for exact specifications and pinout.

Package

QFN-16 package: 4×4 mm leadframe with exposed pad (EP), RoHS-compliant.

Pinout

Pin count: 16 pins (QFN package).
Function: A high‑voltage PWM controller for off‑line switch‑mode power supplies (e.g., flyback). It implements current‑mode regulation with startup, undervoltage protection, soft‑start, protections (OVP/OC), and drives an external power MOSFET.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: A multinational American semiconductor company that designs and manufactures a wide range of integrated circuits and sensors, specializing in analog, mixed-signal, and embedded processing ICs; one of the world's largest semiconductor producers.

Application

Applications: offline AC–DC switch-mode power supplies (isolation flyback with primary-side regulation), AC adapters, telecom/industrial power supplies, battery chargers, LED drivers, and other energy-efficient DC power converters.

Equivalent

There isn’t a published 1:1 cross-reference for UCC5880QDFCRQ1. To find a substitute, provide your application specs (input range, power, startup current, pinout) and use TI’s Cross-Reference tool or contact TI support. If seeking functionally similar TI devices, consider the UCC58xx/UCC38xx high‑voltage PWM controller families, but verify pinout and HV startup behavior to ensure a valid replacement.
