Description
The KA3524 regulating pulse width modulator contains
all of the control circuit necessary to implement switching
regulators of either polarity, transformer coupled DC to
DC converters, transformerless polarity converters and volt-
age doublers, as well as other power control applications.
This device includes a 5V voltage regulator capable of sup-
plying up to 50mA to external circuit , a control ampli-
fier, an oscillator, a pulse width modulator, a phase
splitting flip-flop, dual alternating output switch transistors,
and current limiting and shut-down circuit. Both the regu-
lator output transistor and each output switch are internally
current limiting and, to limit junction temperature, aninter-
nal thermal shutdown circuit is employed.
