Analog Devices LTC3315A | Demoboard DC3123A

Description

Demonstration Circuit DC3123A features the LTC©3315A dual 5V, 2A Synchronous Step-Down DC/DC regulators operating at 2MHz. One regulator provides a 1.2V outputand the other provides 1.8V, both up to a 2A load. The LTC3315A supports adjustable output voltages from 0.5Vto VIN, operating frequencies from 1MHz up to 3MHz. The LTC3315A is a compact, high efficiency, and high speed synchronous monolithic step-down switching regulator.Fast minimum on-time of 25ns enables high VIN to low VOUT conversion at high frequency.
