DC1507A: LTC3632EDD High Efficiency 20mA Monolithic Synchronous Buck Regulator Quick Start Guide
Quick start guide for DC1507A featuring the LTC3632EDD, a 4.5V-50V input, 20mA synchronous buck regulator with 1.8V, 3.3V, and 5V jumper-selectable outputs.
Overview
Demonstration circuit 1507A is a high-efficiency step-down DC/DC converter featuring the LTC3632EDD monolithic synchronous buck regulator. The circuit operates over a wide input voltage range of 4.5V to 50V and is protected against surges up to 60V. It provides jumper-selectable output voltages of 1.8V, 3.3V, and 5V at up to 20mA load current. The LTC3632EDD utilizes internal high-side and synchronous switches with a low 12μA quiescent current and requires no external compensation. The guide includes performance summaries, measurement setup instructions, and guidance on using electrolytic capacitors like the Panasonic EEU-FC2A680L to dampen input ringing.
