Analog Devices LTC3315 | Demoboard DC2747A
Dual 5V, 2A Synchronous Step-Down DC/DCs in 2mm × 2mm LQFN
Overview
| Topology | Buck Converter |
| Input voltage | 2.25-5.5 V |
| Switching frequency | 1900-2100 kHz |
| Output 1 | 1.8 V / 2 A |
| Output 2 | 1.2 V / 2 A |
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.
