BA9700AF General Description


The BA9700A, BA9700AF and BA9700AFV 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.
