VIPER26HDTR

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

VIPER26HDTR 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 GND power_in Ground and MOSFET source, connecting the source of the internal power MOSFET and the controller ground reference.
2 GND power_in Ground and MOSFET source, connecting the source of the internal power MOSFET and the controller ground reference (same net as pin 1).
3 N.C. unconnected Not connected; this pin can be soldered to GND.
4 N.A. passive Not available for user; it is mechanically connected to the controller die pad and should be connected to GND (pins 1, 2) to improve noise immunity.
5 VDD power_in Controller supply with an external storage capacitor to GND; operating range 11.5 to 23.5 V, startup threshold VDDon 12 to 14 V, undervoltage shutdown VDDoff 7 to 9 V, and a ~0.1 µF bypass capacitor recommended close to the IC.
6 LIM input Drain current limitation; an external resistor to GND lowers the current limit below the default IDlim (0.66 to 0.74 A at 25 °C), a capacitor to GND must be below 470 nF, and the pin can be left open for the default limit.
7 FB input Direct feedback, the inverting input of the internal transconductance error amplifier referenced to 3.2 to 3.4 V (3.3 V typ.) with respect to GND; tying FB to GND disables the E/A in isolated designs.
8 COMP passive Compensation node, the output of the internal error amplifier, which uses an RC network to GND for loop stability; in isolated designs it is driven directly by the optocoupler, and the burst mode threshold VCOMPL is 1.1 V typ.
9 N.C. unconnected Not internally connected; must be left floating to ensure a safe clearance distance.
10 N.C. unconnected Not internally connected; must be left floating to ensure a safe clearance distance.
11 N.C. unconnected Not internally connected; must be left floating to ensure a safe clearance distance.
12 N.C. unconnected Not internally connected; must be left floating to ensure a safe clearance distance.
13 DRAIN passive MOSFET drain with 800 V minimum breakdown; the internal high-voltage current source sinks startup charging current from this pin, and PCB copper under the DRAIN pins is needed for heat dissipation.
14 DRAIN passive MOSFET drain with 800 V minimum breakdown; the internal high-voltage current source sinks startup charging current from this pin, and PCB copper under the DRAIN pins is needed for heat dissipation.
15 DRAIN passive MOSFET drain with 800 V minimum breakdown; the internal high-voltage current source sinks startup charging current from this pin, and PCB copper under the DRAIN pins is needed for heat dissipation.
16 DRAIN passive MOSFET drain with 800 V minimum breakdown; the internal high-voltage current source sinks startup charging current from this pin, and PCB copper under the DRAIN pins is needed for heat dissipation.
