STEP-DOWN PULSE CONSTANT VOLTAGE REGULATOR Russian patent published in 1994 - IPC

FIELD: constant voltage regulators. SUBSTANCE: regulator has control unit consisting of comparator, AND-AND logic gate, RS-trigger, generator, transistors, reference voltage source and diode. Regulator includes also control transistor, transistors, LCD-filter, resistive divider, resistors, diode, capacitor, correcting pulse shaper consisting of transistor, resistors, capacitor, unit for separating leading edge of pulse, trigger and actuating element. Natural (non-adjustable) part of duration of interval of control unit is separated from general duration of this unit interval and control transistor is force-rendered operative for duration of the separated part of interval by signal from correcting pulse shaper. EFFECT: regulation of output voltage at lower input voltage. 5 cl, 4 dwg
