MC34063DRG

HANSCHIP semiconductor · DC-DC Converters · SOP-8

MC34063DRG from HANSCHIP semiconductor, in a SOP-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 Switch Collector output Internal switch transistor collector, rated for 40 V collector voltage and up to 1.2 A switch current.
2 Switch Emitter passive Internal switch transistor emitter, rated at 40 V maximum at pin 1 = 40 V.
3 Timing Capacitor passive Timing capacitor connection that sets the switching frequency (up to 180 kHz with CT = 100 pF; datasheet test condition uses CT = 1 nF).
4 GND power_in Ground pin for all internal circuits.
5 Comparator Inverting Input input Inverting input of the internal comparator; comparator input voltage range is -0.3 V to 40 V, with the output voltage set by the divider on this pin against the 1.25 V internal reference.
6 VCC power_in Supply voltage pin, operating from 3 V to 40 V (absolute maximum 40 V).
7 IPK Sense input Peak current sense input that monitors the voltage drop across an external sense resistor Rcs to limit switch peak current (current limit sense voltage 250 to 350 mV; Rcs of 0.2 Ω or more is specified).
8 Driver Collector passive Driver collector voltage pin, rated at 40 V with driver collector current limited to 100 mA.
