Power Management Application Notes
- Leadis LDO Application Demo Board - The Demo board is made in four quadrants, for each family/package option of LDO regulator offered. The four circuits are completely isolated and do not share a common ground.
- Designing Battery Chargers using the LDS120P - The LDS120P is a controller for a constant current/constant voltage supply suitable for charging batteries to a final voltage at a fixed current. The LDS120P is intended to drive an external PNP pass transistor to implement a system for charging Lithium Ion (Li Ion), Nickel metal hydride (NiMH), lead-acid or similar rechargeable batteries.
- Designing Battery Chargers using the LDS105P - The LDS105P is a secondary-side controller for implementing a constant current/constant voltage supply suitable for charging batteries to a final voltage at a fixed current. The LDS105P replaces the conventional TL431-type secondary error amplifier traditionally used for power supply control with a 5 pin SOT-23 device which adds the functionality of sensing limiting the output current
- Designing LDO Regulators using the LDS120P - The LDS120P is a controller for implementing a constant current/constant voltage supply suitable for charging batteries to a final voltage at a fixed current. The basic architecture also allows it to be used to implement very low drop-out regulators using an external power device. Particularly where cost and dropout performance are of paramount importance, LDS120P solutions may have significant advantage over integrated LDO regulators.
