Overview

Topology	Buck Converter
Input voltage	2.25-5.5 V
Switching frequency	1000-3000 kHz
Output 1	1.2 V / 2 A

Description

Demonstration circuit 2419A features the LTC®3372 in a multi-output step-down converter. The controller portion of the LTC3372 drives a high output voltage (HV) buck converter which has an input voltage range of 6V to 60V.Its output voltage (VOUT_HV) is nominally 5V but can be configured for either 5V or 3.3V with the VOUTPRG pin. VOUT_HV supplies power to the configurable buck regulator. This regulator provides four low voltage (LV) outputs labelled VOUT1-4. These outputs are 1.2V/2A, 1.8V/2A, 2.5V/2A and 3.3V/2A respectively. When VOUT_HV is configured for 5V, it can supply 6A to the external loads with full load on VOUT1-4. With no load on VOUT1-4, VOUT_HV can supply 10A to the external loads. See Figure 3 for the Block Diagram.

Features

Selectable light load operating modes of:
- FCM
- Pulse-skipping (HV) and Burst Mode operation (LV)
- Burst Mode operation
PLLIN pin to synchronize the LV regulators over a 1MHz to 3MHz range (166kHz to 500kHz for the HV converter)
Watch dog circuit
TEMP pin to monitor the junction temperature of the LTC3372
PGOOD pin for the HV converter and RST pin for the LV regulators

Typical applications

General Purpose Multi-Channel Power Supplies
Automotive and Industrial Always-On Systems
