Overview

Description

LM5169FDDAR is a Texas Instruments synchronous buck regulator/controller for DC-DC conversion. It’s designed to convert a wide input voltage to a lower regulated output with high efficiency, suitable for automotive, telecom, and industrial applications. Key features typically include current-mode control, adjustable switching frequency, enable and soft-start, and comprehensive protection (undervoltage lockout, overcurrent/short-circuit protection, thermal shutdown). It supports precise output regulation through feedback/remote sensing and can operate in PWM or power-save modes to optimize efficiency. The FDDAR suffix denotes a specific TI packaging/version (RoHS-compliant). For exact electrical specifications, pinout, and application guidelines, consult the TI datasheet and product page. Typical uses include point-of-load VRMs and other DC-DC power supplies requiring wide input range, high efficiency, and tight regulation.

Features

LM5169FDDAR features (highlights):
- Wide input range up to ~60 V, suitable for automotive/industrial supplies
- Synchronous buck regulator with integrated high-side and low-side MOSFETs for high efficiency
- Current-mode control for fast transient response and stable loop
- Adjustable output voltage via external resistor divider
- Programmable soft-start and programmable current limit to limit inrush and protect the device
- Enable input with undervoltage lockout and power-good signaling
- Robust protections: cycle-by-cycle current limit, overvoltage protection, overtemperature shutdown (with latch-off)
- Suitable for wide temperature ranges; RoHS-compliant DDAR package

Package

LM5169FDDAR uses a 16‑pin VQFN (4×4 mm) package with an exposed pad (lead‑free; tape & reel).

Pinout

- Pin count: 16 pins.
- Function: High‑voltage DC‑DC controller (buck/boost) that drives external MOSFETs; uses current‑mode control and includes protections (soft‑start, enable/disable, overcurrent/voltage protections) for regulating the output.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- About the company: TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital ICs and related devices.

Application

- Automotive DC-DC power regulators (load/rail generation in vehicles)
- Industrial and automation power supplies
- Telecom and data-center front-end regulators
- Point-of-load regulators for CPUs/GPUs/ASICs
- Battery and solar energy management systems
- General high-efficiency synchronous buck regulators for various power architectures
