Description

The AP6714 is fully integrated synchronous current mode

boost converter which provides a complete power supply

solution for all one-cell, two-cell, three cell, alkaline, NiCd or

NiMh or single-cell Lithion battery powered products. They

improve performance, component count and size compared

to conventional controllers, lithium-ion (Li+) designs. On-chip

MOSFETs provide up to 94% efficiency for critical power

supplies. This optimizes overall efficiency and cost, while

also reducing board space. Operate at one fixed frequency of

1.8MHz to optimize size, cost, and efficiency. Other features

include soft-start and overload protection. AP6714 is

available in space-saving 10-pin MSOP package.
