The Analog Devices LTM4662EY#PBF is a high-efficiency, high-density, synchronous step-down DC-DC converter. It is designed to provide a regulated output voltage from 0.6V to 5.5V with a maximum output current of 2A. The device is housed in a 16-pin HTSSOP package, making it ideal for space-constrained applications.

Features of the LTM4662EY#PBF include:
- High efficiency: up to 95%
- Low quiescent current: only 10µA
- Wide input voltage range: 0.6V to 5.5V
- Output voltage accuracy: ±1.5%
- Output current limit: 2A
- Over-temperature protection
- Over-voltage protection
- Short-circuit protection
- Soft-start

The LTM4662EY#PBF is suitable for a wide range of applications, including portable electronics, battery-powered systems, and automotive electronics. It is also ideal for powering FPGAs, ASICs, and other low-voltage logic circuits.
