NTE1720
Integrated Circuit
Pulse Width Modulator (PWM) Regulator
Description:
The NTE1720 PWM switching regulator control circuit contains all the essential circuitry to implement
single–ended or push–pull switching regulators. Included on the circuit are oscillator, voltage refer-
ence, a pulse width modulator, error amplifier, overload protection circuitry and output drivers.
A substance zener reference has been used to provide excellent stability with time and the reference
has been used to provide excellent stability with time and the reference is trimmed at the wafer level
to provide an initial accuracy of 2%. Additionally, the oscillator is trimmed to provide a medium toler-
ance of 6%.
