VIPER0PHDTR

STMicroelectronics · AC-DC Controllers And Regulators · SO-16

VIPER0PHDTR from STMicroelectronics, in a SO-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 PGND power_in Power ground and MOSFET source; pulsed current from Power MOSFET must return through this pin and be connected to same ground plane as SGND with shortest trace.
2 EAGND power_in Error amplifier ground reference; connect directly to negative rail for non-isolated negative output converters, or short to SGND for positive output converters.
3 VCC power_in Controller supply voltage; internal high-voltage current source provides VCC capacitor charging current at startup and during steady-state operation; requires external storage capacitor across VCC-SGND and 0.1 μF bypass capacitor placed close to IC.
4 SGND power_in Signal ground; all groundings of bias components must connect to this pin and be kept separate from pulsed current return path.
5 FB input Direct feedback to inverting input of internal transconductance error amplifier, internally referenced to 1.2 V with respect to EAGND; accepts output voltage information via voltage divider.
6 COMP output Compensation output of internal error amplifier; compensation network placed between this pin and SGND to achieve control loop stability and good dynamic performance.
7 ON input ZPM exit control; IC is reactivated by forcing this pin to SGND for debounce time tDEB_ON; internal pull-up resistor keeps pin at VON level during normal operation.
8 OFF input ZPM enter control; IC enters ZPM by forcing this pin to SGND for debounce time tDEB_OFF; internal pull-up resistor keeps pin at VOFF level during normal operation.
9 N.C. unconnected Not internally connected; must be left floating to maintain safe clearance distance.
10 N.C. unconnected Not internally connected; must be left floating to maintain safe clearance distance.
11 N.C. unconnected Not internally connected; must be left floating to maintain safe clearance distance.
12 N.C. unconnected Not internally connected; must be left floating to maintain safe clearance distance.
13 DRAIN output MOSFET drain; internal high-voltage current source sinks current from this pin to charge VCC capacitor at startup and during steady-state operation; mechanically connected to internal metal PAD for heat dissipation.
14 DRAIN output MOSFET drain; internal high-voltage current source sinks current from this pin to charge VCC capacitor at startup and during steady-state operation; mechanically connected to internal metal PAD for heat dissipation.
15 DRAIN output MOSFET drain; internal high-voltage current source sinks current from this pin to charge VCC capacitor at startup and during steady-state operation; mechanically connected to internal metal PAD for heat dissipation.
16 DRAIN output MOSFET drain; internal high-voltage current source sinks current from this pin to charge VCC capacitor at startup and during steady-state operation; mechanically connected to internal metal PAD for heat dissipation.
