SG3525S
IDCHIP · DC-DC Converters · DIP-16
SG3525S from IDCHIP, in a DIP-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, with a common-mode range of +1.5 V to +5.2 V that includes the 5.1 V reference. |
| 2 | Noninv. Input | input | Noninverting input of the error amplifier, with a common-mode range of +1.5 V to +5.2 V that includes the 5.1 V reference. |
| 3 | Sync | bidirectional | Oscillator synchronization pin that allows master-slave operation or synchronization to an external clock, with a sync threshold of 1.2 to 2.8 V. |
| 4 | OSC. Output | output | Oscillator clock output, typically 3.5 V high with a 0.5 µs pulse width. |
| 5 | CT | passive | Oscillator timing capacitor connection, recommended range 0.001 to 0.2 µF. |
| 6 | RT | passive | Oscillator timing resistor connection to ground, recommended range 2.0 to 150 kΩ. |
| 7 | Discharge | passive | Oscillator discharge pin where a resistor RD (0 to 500 Ω) to CT sets the dead time. |
| 8 | Soft-Start | passive | Soft-start capacitor pin with a 50 µA (25 to 80 µA) pull-up current source, which is discharged when shutdown is asserted or Vcc is under-voltage. |
| 9 | Compensation | bidirectional | Error amplifier output for loop compensation, which has a pull-up current source so a pull-down of 100 µA can shut off the outputs. |
| 10 | Shutdown | input | Shutdown input that, when high, immediately acts on the PWM latch and discharges the soft-start capacitor at 100 µA; it must not be left floating. |
| 11 | Output A | output | Totem-pole output A that sinks and sources up to ±100 mA continuous (±400 mA peak). |
| 12 | Ground | power_in | Ground reference for the device. |
| 13 | VC | power_in | Collector supply for the output stage, recommended 4.5 to 35 V (absolute maximum +40 V). |
| 14 | Output B | output | Totem-pole output B that sinks and sources up to ±100 mA continuous (±400 mA peak). |
| 15 | VCC | power_in | Supply voltage input, recommended 8.0 to 35 V (absolute maximum +40 V). |
| 16 | Vref | power_out | Reference output of 5.1 V ±1.0% (5.00 to 5.20 V), with load current of 0 to 20 mA and short-circuit current typically 80 mA. |
