General Description

The CA1524 and CA3524 are silicon monolithic integrated circuits designed to provide all the control circuitry for use in a broad range of switching regulator circuits.

The CA1524 and CA3524 have all the

Key Features

of the industry types SG1524, SG2524, and SG3524, respectively. A block diagram of the CA1524 series is shown in Figure 1. The circuit includes a zener voltage reference, transconductance error ampliﬁer, precision R-C oscillator, pulse-width modulator, pulse-steering ﬂip-ﬂop, dual alternating output switches, and current-limiting and shutdown circuitry. This device can be used for switching regulators of either polarity, transformer-coupled dc-dc converter, transformerless voltage doublers, dc-a.
