Texas Instruments MC34063AD, 1-Channel, Inverting, Step-Down/Up DC-DC Converter 8-Pin, SOIC

The Texas Instruments devices are easy-to-use ICs containing all the primary circuitry needed for building simple DC-DC converters. These devices primarily consist of an internal temperature-compensated reference, a comparator, an oscillator, a PWM controller with active current limiting, a driver, and a high-current output switch. Thus, the devices require minimal external components to build converters in the boost, buck, and inverting topologies.

Wide Input Voltage Range: 3 V to 40 V
High Output Switch Current: Up to 1.5 A
Adjustable Output Voltage
Oscillator Frequency Up to 100 kHz
Precision Internal Reference: 2%
Short-Circuit Current Limiting
Low Standby Current
