Overview

Description

LT3972EMSE#TRPBF is the Linear Technology (Analog Devices) LT3972 LED-driver IC in the EMSE package, with Pb-free Tape-and-Reel packaging. The LT3972 is a high-efficiency switching regulator designed to drive LED strings with a precise constant-current output. The EMSE suffix denotes the specific package variant, while #TRPBF indicates Tape-and-Reel, Pb-free packaging for automated assembly.
Typical use: constant-current LED driving (e.g., backlighting, signage, automotive lighting) with external components (inductor, sense resistor, capacitors) per the datasheet. It supports adjustable LED current via a sense resistor and common dimming options (e.g., PWM).
For exact electrical specifications, pinout, and application notes, consult the LT3972 datasheet and product page on Analog Devices’ site.

Features

LT3972EMSE#TRPBF features (concise):
- Dual synchronous buck regulator controllers (two channels)
- Wide input range suitable for automotive/applications (up to ~60V)
- Current-mode control with fast transient response
- Independent regulation per channel
- Fixed-frequency PWM with optional synchronization
- Internal gate drivers for high-side/low-side MOSFETs (synchronous rectification)
- Adjustable output voltages per channel via external feedback
- External compensation (Vc) per channel
- Soft-start and channel-to-channel sequencing/tracking
- Enable/shutdown control per channel
- Protections: overcurrent/short-circuit, overvoltage, thermal shutdown (with latch)
- Power-Good/status indicators
- Small MSOP-8 package (EMSE), Pb-free, Tape & Reel (TRPBF)
Note: Exact voltage ranges, frequencies, and pin functions are per datasheet.

Package

LT3972EMSE#TRPBF uses an MSOP-8 package with an exposed pad (MSE). Pb-free, Tape-and-Reel packaging.

Pinout

Pin count: 8 pins (MSOP with exposed pad, EMSE).
Function: LT3972EMSE#TRPBF is a dual synchronous buck regulator controller (two-channel step-down DC-DC converter).

Manufacturer

Analog Devices, Inc. The LT3972 originates from Linear Technology, which Analog Devices acquired in 2017. Analog Devices is a global semiconductor company focused on analog, mixed-signal, and DSP ICs, including power-management and signal-processing products.

Application

LT3972EMSE#TRPBF is a high-voltage DC-DC controller used in wide-input power converters. Typical application areas include:
- Automotive power modules (12–60V automotive rails)
- Industrial DC-DC regulators
- Telecom/network equipment power rails
- Solar/battery-backup and UPS systems
- Battery-powered handheld/portable devices
- Post-regulation and multi-rail PMIC applications
