BA9700AFV

开关稳压器的DC / DC转换器 Switching regulator for DC / DC Converters

Switching regulator for DC / DC Converters

The BA9700A, BA9700AF and are switching regulators that use a pulse width modulation PWM system. They use a transistor switch to stabilize the output voltage. By the use of the transistor, power loss is decreased, fluctuation efficiency is improved, and the circuit is made more compact and single.

!Features

1 Output voltage can step up, step down, or invert at an arbitrary level.
