The MC33063A-Q1 device is an easy-to-use IC containing all the primary circuitry needed for building simple DC-DC converters. The device primarily consists 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 device requires minimal external components to build converters in the boost, buck, and inverting topologies.

The MC33063A-Q1 device is characterized for operation from –40°C to 125°C.

TIDA-01168 — Bidirectional DC/DC Converter Reference Design for 12-V/48-V Automotive Systems

The TIDA-01168 reference design is a four-phase, bidirectional DC-DC converter development platform for 12-V/48-V automotive systems. The system uses two LM5170-Q1 current controllers and a TMS320F28027F microcontroller (MCU) for the power stage control. LM5170-Q1 subsystems use average current (...)
