ML4894
Synchronous Buck Controller
GENERAL DESCRIPTION
The ML4894 synchronous buck controller has been
designed to provide high efficiency DC/DC conversion for
portable products. The ML4894 can deliver a fixed 5V
output from input voltages of 5.9V to 15V.
The ML4894 drives external P- and N-channel MOSFETs
in a synchronous buck topology, allowing an overall
conversion efficiency of greater than 90% over an output
current range exceeding three decades, with an output
current capability of up to 5A.
The regulator can be disabled via the
SHDN
pin. While
disabled, the output of the regulator is completely
isolated from the circuit鈥檚 input supply, and the supply
current is reduced to less than 5碌A(chǔ) to help extend battery
life.
