LM2578AN

Texas Instruments · DC-DC Converters · PDIP-8

LM2578AN from Texas Instruments, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 -INPUT input Inverting comparator input with an internal 1.0V reference; the feedback input used for buck, boost and inverting configurations.
2 +INPUT input Non-inverting comparator input with an internal 1.0V reference; any external voltage applied above the reference must be limited to less than 5 mA.
3 OSC passive Oscillator pin where a single external timing capacitor sets the switching frequency from <1 Hz to 100 kHz, fOSC = 8x10^-5/C1.
4 GND power_in Ground; the emitter must not be pulled more than 1V below this pin (0.6V for TJ >= 100°C).
5 EMITTER output Emitter of the 750 mA output transistor, which must not be driven more than 1V below ground and is rated -1V to +50V.
6 COLLECTOR output Collector of the 750 mA output transistor, rated -0.3V to +50V with saturation voltage under 0.9V.
7 CURRENT LIMIT input Cycle-by-cycle current limit terminal referenced to either VIN or ground, activating when pulled 110 mV away from either.
8 VIN power_in Supply input operating from 2V to 40V, with total supply voltage rated at 50V maximum.
