BA9700A / BA9700AF / BA9700AFV
Regulator ICs
Switching regulator for DC / DC Converters
BA9700A / BA9700AF / BA9700AFV
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.
!Features 1) Output
voltage can step up, step down, or invert at an arbitrary level.
