NJM2374AM-TE1-#ZZZB

JRC · DC-DC Converters · SOIC-8-208mil

NJM2374AM-TE1-#ZZZB from JRC, in a SOIC-8-208mil. 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 CS output Collector of the internal output power transistor, tied to CD for the Darlington connection in the Vsat1 test condition (CS=CD).
2 ES passive Emitter of the internal output power transistor, tested with ES=GND; the switch rating is 1.5 A maximum.
3 CT passive Oscillator timing capacitor pin; oscillator frequency and switch ON/OFF time are specified against CT, with CT=1nF used for operating current tests.
4 GND power_in Ground reference pin for the device.
5 IN+ input Non-inverting error amplifier input compared against the 1.25 V (±2%) threshold Vth, with input bias current specified at 400 nA maximum.
6 V+ power_in Supply input rated 2.5 V (minimum 3.0 V at low temperature) to 40 V maximum; the NJM2374AE variant is rated to 48 V.
7 SI input Logic input that the datasheet only shows in test conditions (SI=V+); its function is not described in the text.
8 CD output Driver output for the internal power transistor; the Vsat2 test specifies Ic(driver) of 50 mA with forced beta of about 14.
