Visão Geral

Description

The TPS84410RKGR is a high-efficiency, 4-A step-down (buck) DC/DC converter module from Texas Instruments. It integrates power MOSFETs, an inductor, and passives into a compact 3.5-mm × 4-mm QFN package, simplifying design and saving board space.
Key features:
- Input voltage range: 2.95 V to 6 V
- Output voltage: Adjustable (0.6 V to 5.5 V)
- Efficiency: Up to 95%
- Switching frequency: 1.25 MHz (fixed)
- Load capability: 4 A continuous
- Protections: Overcurrent, overtemperature, and undervoltage lockout
Ideal for point-of-load (POL) regulation in space-constrained applications like FPGAs, ASICs, and networking equipment. The module requires minimal external components, reducing design complexity and time-to-market.
For detailed specs, refer to the [TI datasheet](https://www.ti.com/product/TPS84410).

Equivalent

The TPS84410RKGR is a 4A, 17V input synchronous buck converter with PMBus. Equivalent alternatives include:
1. LTC3824 - Similar specs, no PMBus.
2. LM5145 - Higher current (5A), PMBus support.
3. TPS544B25 - 4A, PMBus, adjustable output.
4. MAX15062 - 4A, no PMBus but compact.
Check pin compatibility and specs before substitution. For exact PMBus features, TPS544B25 is the closest match.
