Description

Demonstration Circuit DC2747A features the LTC©3315A dual 5V, 2A Synchronous Step-Down DC/DC regulators operating at 2.0MHz. One regulator provides a 1.2V output and the other provides 1.8V, both up to a 2A load. The LTC3315A supports adjustable output voltages from 0.5V to 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.
