The MC34063ADR2G from On Semiconductor is a monolithic control circuit designed for DC-to-DC converters. It integrates essential functions including a temperature-compensated reference, comparator, controlled duty cycle oscillator with current limit, driver, and a high-current output switch. This device is suitable for step-down, step-up, and voltage-inverting applications, requiring a minimal number of external components.
Key electrical specifications include an input voltage range of 3.0 V to 40 V and an output switch current capability of up to 1.5 A. The switching frequency can operate up to 100 kHz. The output voltage is adjustable, and the device can be configured for positive or negative output.
Packaged in an 8-SOIC surface mount package, the MC34063ADR2G operates within a temperature range of 0°C to 70°C. It is Pb-free and halogen-free, complying with RoHS standards.
