NCP12700ADNR2G
onsemi · AC-DC Controllers And Regulators · MSOP-10
NCP12700ADNR2G from onsemi, in a MSOP-10. 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 | UVLO | input | Input to the standby and UVLO comparators, where a resistor divider from the supply input to ground sets the enable voltage, hysteresis is set by a 5 A pull-down current source, and an external pull-down signal can disable the controller. |
| 2 | FLT | bidirectional | Input to a window comparator with upper and lower fault thresholds, where tripping either threshold enters fault mode (permanent latch-off or a minimum 1 s auto-recovery period), and a precision current source drives an NTC to ground for over-temperature protection. |
| 3 | SS | bidirectional | Sets the soft-start ramp of the peak current limit when the controller is enabled, using an internal 15 A current source and an external capacitor to ground, with typical soft-start capacitor values of 10 nF to 100 nF. |
| 4 | RT | input | Sets the oscillator frequency and requires a resistor to ground located close to the IC, with typical RT values in the range of 10 k to 100 k. |
| 5 | COMP | passive | Provides the compensated error voltage for the PWM and skip comparators and includes an internal 5 k pull-up resistor that can be used to bias an opto-coupler transistor. |
| 6 | CS | input | Current sense input for the PWM and current limit comparators, whose input is held low for 60 ns after DRV goes high to blank leading-edge spikes, with an external low-pass filter recommended and its resistor also setting the over-power protection applied to the sense signal. |
| 7 | GND | power_in | Controller ground pin. |
| 8 | DRV | output | High-current output that drives the external MOSFET gate, with source capability of 1 A and sink capability of 2.8 A. |
| 9 | VCC | power_in | Bias supply for the controller, with an external decoupling capacitor of 1 to 10 F to ground recommended and a recommended supply voltage of 9 to 20 V. |
| 10 | VIN | power_in | Input to the high-voltage startup regulator, which sources more than 15 mA to temporarily bias VCC during startup, with a maximum high-voltage startup voltage of 120 V for MSOP10 and recommended VIN of 9 to 100 V. |
