SG1524BJ is a low-power monolithic switching regulator control circuit designed for use in a wide range of switched mode power supplies and other similar control circuitry. The circuit is functionally equivalent to the SG1524 and SG3842 devices with added infrared compensation. It utilizes a combination of bipolar and MOSFET transistors to provide low power operation, high efficiency and low output voltage ripple. The circuit includes on-chip oscillator, PWM control circuitry and error compensation circuitry. It includes an enable terminal that can accommodate both TTL and CMOS logic inputs and it is available in an 8 pin plastic DIL package.
