Analog Devices LTC3309A | Demoboard DC2745A
LTC3309A 5V, 6A Synchronous Step-Down Silent Switcher in 2mm × 2mm LQFN
Overview
| Topology | Buck Converter |
| Input voltage | 2.25-5.5 V |
| Switching frequency | 1000-3000 kHz |
| Output 1 | 1.22 V / 6 A |
Description
Demonstration Circuit 2745A features the LTC®3309A 5V, 6A synchronous step-down silent switcher operating as a 2MHz, 3.3V to 1.2V 6A buck regulator. The LTC3309A supports adjustable output voltages from 0.5V to VIN, and operating frequencies from 1MHz up to 3MHz. The LTC3309A is a compact, ultralow emission, high efficiency, and high speed synchronous monolithic stepdown switching regulator. A minimum on-time of 22ns enables high VIN to low VOUT conversion ratios at high switching frequencies.
