■ DESCRIPTION
be used as step-up, step-down and inverting regulators.
transistor. The output voltage is controled by PWM method.
to the pin 2. The amplifier is 80dB open-loop voltage gain and 1MHz band width. By adding adequate resistors to the pin
1, the indicating signal comes when the input voltage drops more than designed input voltage. Switching transistor is
open collector.
