HGSEMI · AC-DC Controllers And Regulators · SOP-16

SG3524M from HGSEMI, in a SOP-16. 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 INV. INPUT input Inverting input of the error amplifier; recommended common-mode input range is 1.8 to 3.4 V.
2 N.I. INPUT input Non-inverting input of the error amplifier; recommended common-mode input range is 1.8 to 3.4 V.
3 OSC. OUTPUT output Oscillator output providing the sawtooth/clock signal, usable for external synchronization.
4 +C.L. SENSE input Positive input of the current limit amplifier; differential sense voltage limited to -0.3 to 0.3 V with a threshold of about 200 mV (180 to 220 mV).
5 -C.L. SENSE input Negative input of the current limit amplifier; differential sense voltage limited to -0.3 to 0.3 V.
6 RT passive Oscillator timing resistor connection; recommended RT is 1.8 to 100 kΩ.
7 CT passive Oscillator timing capacitor connection; recommended CT is 1 to 1000 nF.
8 GROUND power_in Ground reference for the device.
9 COMPENSATION passive Error amplifier output for loop compensation, which also feeds the PWM comparator.
10 SHUTDOWN input Shutdown input with a threshold voltage of 0.5 to 1.2 V (typically 0.8 V) that disables the outputs.
11 EA passive Emitter of output transistor A; emitter output voltage is rated at 17 V at IE = 50 mA.
12 CA passive Collector of output transistor A; collector voltage is 0 to 40 V and output current is 0 to 50 mA recommended.
13 CB passive Collector of output transistor B; collector voltage is 0 to 40 V and output current is 0 to 50 mA recommended.
14 EB passive Emitter of output transistor B; emitter output voltage is rated at 17 V at IE = 50 mA.
15 +VIN power_in Supply input; recommended 8 to 40 V and absolute maximum 42 V.
16 VREF power_out 5 V reference output (4.8 to 5.2 V) with a recommended load of 0 to 20 mA.
