概述

Description

LM5032MTCX/NOPB is Texas Instruments’ LM5032 device—a high-voltage, fixed-frequency, current-mode PWM controller used for switch‑mode power supplies. It’s a controller (external MOSFET required) suitable for buck, boost, buck‑boost, and flyback topologies (offline and isolated/non‑isolated applications). Key features typically include peak current‑mode control, programmable switching frequency, soft‑start, enable/disable input, undervoltage lockout, overcurrent protection, and thermal shutdown/fault reporting. The MTCX suffix denotes the package type (a 20‑pin TSSOP/SO package variant), and NOPB indicates Pb‑free, RoHS-compliant construction. Common applications include switching power supplies, adapters, LED drivers, and automotive/industrial DC‑DC converters. For exact electrical specs (input voltage range, frequency, current limit, startup current, etc.), consult the LM5032 datasheet on TI’s website.

Features

Here are the key features of LM5032MTCX/NOPB (TI, Pb-free):
- High-voltage PWM controller (primary-side) suitable for off-line flyback/buck-boost topologies
- Up to 600 V input range (start-up/operating)
- Current-mode control with slope compensation
- Programmable switching frequency
- Enable input with undervoltage lockout
- Soft-start to limit inrush
- Protection: overcurrent/short-circuit with latch or hiccup, overvoltage, thermal shutdown
- External feedback for precise voltage regulation
- Suitable for LED driver applications and general isolated/non-isolated power supplies
- 8-pin MTCX package, RoHS-compliant (NOPB)
Note: For exact electrical specifications (voltage ranges, current limits, frequency range, pinout, etc.), please refer to the official datasheet.

Package

LM5032MTCX/NOPB comes in a 16‑pin HTSSOP package with Pb‑free (NOPB).

Pinout

LM5032MTCX/NOPB is an 8-pin device (MSOP-8 package).
Pin functions (typical for this PWM controller):
- GATE: Output drive to the external MOSFET gate.
- IS: Current-sense input for peak current regulation.
- FB: Feedback input from the output (voltage feedback).
- COMP: Error-amplifier compensation node.
- RT/CT: Oscillator timing resistor/capacitor input (sets switching frequency).
- VCC: Supply for internal circuitry.
- GND: Ground reference.
- EN (or SHDN/UVLO): Enable/disable (and undervoltage lockout) input.
Note: Pin names can vary slightly by package variant; refer to the specific datasheet for exact pin mapping.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits, including power-management devices, for numerous industries.

Application

LM5032MTCX/NOPB is a high-voltage PWM controller for offline switch‑mode power supplies. Typical applications: universal-input AC‑DC power supplies (flyback/forward topologies), isolated DC‑DC converters for telecom/industrial equipment, high-efficiency adapters, battery chargers, and other general SMPS/controllers in consumer electronics.
