The MAX1566/MAX1567 provide a complete powersupply solution for digital cameras. They improve performance, component count, and size compared to conventional multichannel controllers in 2-cell AA, 1-cell lithium-ion (Li+), and dual-battery designs. On-chip MOSFETs provide up to 95% efficiency for critical power supplies, while additional channels operate with external FETs for optimum design flexibility. This optimizes overall efficiency and cost, while also reducing board space.
The MAX1566/MAX1567 include six high-efficiency DC-to-DC conversion channels:
- Step-up DC-to-DC converter with on-chip power FETs
- Main DC-to-DC converter with on-chip FETs, configurable to step either up or down
- Step-down core DC-to-DC converter with on-chip FETs
- DC-to-DC controller for white LEDs or other output
- Extra DC-to-DC controller (typically for LCD); two extra controllers on the MAX1566
- Transformerless inverting DC-to-DC controller (typically for negative CCD bias) on the MAX1567
Applications
- Digital Cameras
- PDAs
