UC2524ADW from Texas Instruments, in a SOIC-16-300mil. 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, which has an input range that includes 5V. |
| 2 | Non-Inv Input | input | Non-inverting input of the error amplifier, which has an input range that includes 5V. |
| 3 | OSC/Sync | bidirectional | Oscillator output/synchronization pin, usable to synchronize with an external clock pulse (oscillator usable beyond 500kHz). |
| 4 | C.L. (+) Sense | input | Non-inverting input of the current limit amplifier, which has about 200mV offset (190-210mV typical limit at 25°C). |
| 5 | C.L. (-) Sense | input | Inverting input of the current limit amplifier; common-mode range is -0.3V to +5.5V. |
| 6 | RT | passive | Oscillator timing resistor connection that sets the oscillator frequency together with CT. |
| 7 | CT | passive | Oscillator timing capacitor connection that sets the oscillator frequency together with RT. |
| 8 | Ground | power_in | Ground reference for the device. |
| 9 | Compensation | output | Error amplifier output for loop compensation, feeding the PWM comparator; maximum forced voltage -3 to +5V and forced current ±10mA. |
| 10 | Shutdown | input | External shutdown input acting through the PWM latch with 200ns response; maximum forced voltage -3 to +5V and forced current ±10mA. |
| 11 | Emitter A | passive | Emitter of uncommitted output transistor A, rated for 200mA output current. |
| 12 | Collector A | passive | Collector of uncommitted output transistor A, rated for 60V and 200mA. |
| 13 | Collector B | passive | Collector of uncommitted output transistor B, rated for 60V and 200mA. |
| 14 | Emitter B | passive | Emitter of uncommitted output transistor B, rated for 200mA output current. |
| 15 | +VIN | power_in | Supply input with 8V to 40V operating range after turn-on (40V absolute maximum) and undervoltage lockout turn-on threshold of 7.5V typical. |
| 16 | +5V VREF | power_out | Precision 5V reference output trimmed to ±1% with 50mA maximum reference output current. |
