  • Separate Outputs for Single-Ended or Push-Pull Operation
  • Line and Load Regulation 0.2%(Typ)
  • Internal Reference Supply with 1% (Max) Oscillator and Reference Voltage Variation Over Full Temperature Range
  • Standby Current of Less Than 10mA
  • Frequency of Operation Beyond 100kHz
  • Variable-Output Dead Time of 0.5µs to 5µs
  • Low VCE(sat) Over the Temperature Range

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 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-ac power inverters, highly efficient variable power supplies, and polarity converter, as well as other power-control applications.

Applications

  • Positive and Negative Regulated Supplies
  • Dual-Output Regulators
  • Flyback Converters
  • DC-DC Transformer-Coupled Regulating Converters
  • Single-Ended DC-DC Converters
  • Variable Power Supplies
