NCP1252DDR2G

onsemi · DC-DC Converters · SOIC-8

NCP1252DDR2G from onsemi, in a SOIC-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 FB input This pin directly connects to an optocoupler collector and provides the feedback input.
2 BO input This Brown-out input monitors the input voltage image to offer Brown-out protection.
3 CS input The current sense pin monitors the primary current and allows selection of the ramp compensation amplitude.
4 RT passive A timing resistor connected to ground fixes the switching frequency (adjustable up to 500 kHz per the features list).
5 GND power_in This is the controller ground pin.
6 Drv output This driver pin connects to the MOSFET gate; the maximum voltage on the DRV pin is −0.3 V to VCC.
7 VCC power_in This pin accepts a supply voltage range from 8 V up to 28 V (28 V continuous maximum, 30 V transient for 10 ms with IVcc < 20 mA; maximum injected current 20 mA).
8 SSTART passive A capacitor connected to ground selects the soft-start duration; the soft start is grounded during the delay timer.
