ACE713C

High Efficiency 1.25MHz, 2.5A Boost Regulator

VER 1.2

1

Description

The ACE713C is a high efficiency boost switching regulator especially designed for single cell lithium

battery powered applications. It generates an output voltage of up to 5.5V from an input voltage as low as

2.7V. Ideal for applications where space is limited, it switches at 1.25MHz, allowing the use of tiny, low

cost and low-profile

external components, minimizes solution footprint. Its internal 2.5A, 80mΩ NMOS

switch provides high efficiency even at heavy load, while the constant frequency, current mode

architecture results in low, predictable output noise that is easy to filter. Internal frequency compensation

is designed to accommodate ceramic output capacitors, further reducing noise.
