Description

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 All DC-to-DC channels operate at one fixed frequency settable from 100kHz to 1MHz to optimize size, cost, and efficiency. Other features include soft-start, power-OK outputs, and overload protection. The MAX1566/MAX1567 are available in space-saving 40-pin thin QFN packages. An evaluation kit is available to expedite designs.
