Linear Technology DC2341A Demo Manual

DESCRIPTION LTC7130EY 20V 20A Monolithic Buck Converter with Ultra-Low DCR Sensing Demonstration circuit 2341A is a high efficiency syn- chronous buck DC/DC converter with 4.5V to 20V input range. It can supply 20A maximum load current at 1.5V output. The demo board features the LTC®7130 regulator. No external MOSFETs are requ ...

QUICK START PROCEDURE Demonstration circuit 2341A is easy to set up to evaluate the performance of the LTC7130. Refer to Figure 1 for the proper measurement equipment setup and follow the procedure below: 1. With power off, connect the input power supply to VIN (4.5V to 20V) and GND (input return). 2. Connect the 1.5V output lo ...
