Overview

TopologyBuck Converter
Input voltage3.8-20 V
Output 13.3 V / 0.5 A

Description

Demo circuit DC2491A features the LT®3045EDD, a 500mA,ultralow noise and ultrahigh power supply rejectionratio (PSRR) low dropout (LDO) regulator with programmablecurrent limit.DC2491A operates over an input voltage range of 3.8Vto 20V. The LT3045 delivers a maximum output currentof 500mA. In addition to featuring ultralow noise andultrahigh PSRR, the regulator offers programmable powergood functionality as well as programmable current limit.Current monitoring is also achieved by sensing the ILIMpin voltage.Built-in protection includes reverse battery protection,reverse current protection, internal current limit withfoldback, and thermal limit with hysteresis.L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of LinearTechnology Corporation.
