Overview
| Topology | Push-Pull Converter symmetrical isolated |
| Input voltage | 10-15.5 V |
| Output 1 | 12 V / 0.2 A |
| Output 2 | -12 V / 0.2 A |
Description
The DC2049A demonstrates how a power supply regulatestwo output voltage by using the LT®3999 and low dropout(LDO) regulators.The LT3999 is a monolithic push-pull DC/DC driver whichfeatures wide input range and small external passivecomponents.The LT3999 has duty circle control for ΔVIN compensation,which allows for a wide input voltage range and lowLDO losses.
