The 100kHz switching frequency is on the low side by modern standards — expect larger inductor values (typically 100–470 µH) compared to a 500 kHz+ part, but the switching losses are correspondingly lower. The 3V minimum input lets it run from a 2-cell Li-ion or 3.3V rail, while the 40V maximum input and switch voltage cover 24V industrial supplies and automotive nominal 12V systems with headroom. ## 8-DIP through-hole — rework and prototype fit The 8-DIP (0.300\" width, 7.62mm pitch) through-hole package is a rework technician's friend — no hot-air profile needed, just a soldering iron and desoldering wick. It sits in a standard DIP socket or solders directly into plated through-holes on a 0.100\" grid prototype board.","metaTitle":"MC34063AP DC-DC Converter, Step-Up/Down, 1.5A Switch, 100kHz","metaDescription":"MC34063AP switching regulator IC from ON Semiconductor.
