This is a 1.5A (switch) DC-DC converter supporting both step-up (boost) and step-down (buck) topologies, with a single adjustable output configurable as positive or negative. 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.
