Overview

Description

UCC23514SDWVR is a Texas Instruments power-management IC in the UCC23514 family, used to build offline switch‑mode power supplies. It is a high‑voltage switcher/controller (commonly flyback topology) intended for applications such as AC adapters, charger bricks, and LED drivers. The device provides robust protection features (current limit/OC, undervoltage lockout, thermal protection) and efficient switching across a wide input range. The SDWVR suffix identifies a specific packaging/temperature variant from TI (DWV packaging with RoHS/commercial options). Variants in the UCC23514 family differ in details such as whether the high‑voltage FET is integrated or external, pinout, and timing options. For exact electrical specs (input range, HV rating, switching frequency, startup current) and recommended designs, consult the TI product page and the UCC23514 datasheet. If you share your target input/output requirements, I can point you to the most suitable variant and design resources.

Features

Key features of UCC23514SDWVR:
- High-voltage isolated flyback controller with primary-side regulation (PSR); no optocoupler required
- Integrated startup current source and bias management for offline operation
- Robust gate-drive capability for the MOSFET (high peak drive current for fast switching)
- Wide input range suitable for offline supplies and flyback topologies
- Valley-switching/low-loss operation to boost efficiency
- Comprehensive protection: undervoltage lockout, overcurrent/short-circuit protection with hiccup, overvoltage protection, and thermal shutdown
- Fixed-frequency operation with internal timing; stable performance across conditions
- Compact SDWVR package with TI quality and reliability
Note: For exact electrical specs (voltage ratings, current, timing), refer to the datasheet.

Package

UCC23514SDWVR is in a VQFN-20 package (20-pin) with an exposed thermal pad.

Pinout

- Pin count: 8 pins (in the SDWVR package).
- Function: TI UCC23514 is a high‑voltage primary‑side regulation controller with an integrated MOSFET for isolated flyback switching power supplies. It provides PWM control (valley switching), regulation (PSR), and protections (OV/OC/UV/OT) without requiring an opto‑coupler.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI)
- What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits for automotive, industrial, consumer, and other markets.

Application

UCC23514SDWVR is a high-voltage isolated gate driver for power MOSFETs/IGBTs. Key applications include:
- Offline/primary-side and flyback/forward switch-mode power supplies
- Telecom, datacom, and data-center power modules
- Industrial motor drives
- Solar inverters and energy-storage/battery chargers
- Uninterruptible Power Supplies (UPS) and other high-voltage SMPS topologies

Equivalent

There isn’t a single direct cross-reference for UCC23514SDWVR—the equivalent parts depend on its function and specs. Please share the intended application and key parameters (isolation voltage, number of channels, Vcc/Vlogic, drive current, packaging). I can then provide precise substitutes from TI and other vendors (e.g., ON Semiconductor, Infineon, NXP) based on those requirements.
