Overview
| Topology | Buck Converter |
| Input voltage | 3.8-20 V |
| Output 1 | 3.3 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. All other trademarks are the property of their respective owners.PERFORMANCE SUMMARYThe LT3045 data sheet gives a complete description of thedevice, operation and applications information. The datasheet must be read in conjunction with this demo manualfor DC2491A. The LT3045EDD is assembled in a 10-lead(3mm × 3mm) plastic DFN package with an exposed padon the bottom-side of the IC. Proper board layout is essentialfor maximum thermal performance.
