Details
Switching regulator for DC / DC ConvertersThe 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. 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) 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).
