BA9700AFV Switching regulator for DC / DC Converters

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 ef.

Features

1) Output voltage can step up, step down, or invert at an arbitrary level. 2) Low current consumption. (typically 1.7mA) 3) Wide oscillation frequency range. (typically 2.8k ~ 470kHz) 4) Built-in reference voltage current. (typically 2.57V) 5) Operates at low voltage. (minimally 3.55V) !Block diagram NON INVERT INPUT 14 1/2 Vref 13 INVERT INPUT 12 Vref 11 6) Dead time controller restricts operation when overloaded. 7) Power switch can isolate all circuits in the IC. 8) Best suited for battery operated equipment. 9) Compact 14-pin SSOP package (BA9700AFV).
