NJM2374AE-TE1-#ZZZB

JRC · DC-DC Converters · SOP-8

NJM2374AE-TE1-#ZZZB from JRC, 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 CS passive Collector of the internal 1.5A (max.) output switch transistor; the switch has a 40V (NJM2374AE: 48V) maximum output switch voltage rating.
2 ES passive Emitter of the internal output switch transistor, rated for 1.5A maximum switch current.
3 CT passive Timing capacitor connection that sets the oscillator frequency (100Hz to 100kHz range).
4 GND power_in Ground pin of the IC.
5 IN+ input Error amplifier/comparator input compared against the 1.25V (±2%) reference threshold, with input range -0.3V to 48V on the NJM2374AE.
6 V+ power_in Supply voltage input, operating range 2.5V to 48V for the NJM2374AE (maximum 48V).
7 SI input Peak current sense input (Ipk sense threshold Vth=300mV) used for the over current limit circuit.
8 CD passive Driver collector of the output switch (Darlington connection when tied to CS).
