VP3481MSG10-A

VIVA · DC-DC Converters · MSOP-10

VP3481MSG10-A from VIVA, 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 ISEN input Current sense input: an external resistor in series with ground sets the current limit, which activates when the voltage between ISEN and ground exceeds 230mV.
2 UVLO input Undervoltage lockout input: an external resistor divider sets the input voltage at which switching is enabled and the hysteresis at which it is disabled, compared against an internal 1.43V reference with a 4.5µA source current.
3 COMP input Error amplifier compensation pin, where an RC or C network is used for loop compensation.
4 FB input Output voltage feedback input from an external resistor divider, regulated to the internal 1.275V reference; overvoltage protection is triggered when FB rises to VFB+VOVP.
5 AGND power_in Analog ground, to be connected to the exposed pad.
6 FADJ input Frequency adjust, clock synchronization and shutdown pin: a resistor to ground sets the oscillator frequency (100kHz to 1MHz), an external clock can synchronize the device, and holding the pin high for 30µs or more shuts the device down.
7 PVSS power_in Power ground, to be connected to the exposed pad.
8 GATE output Gate drive output that connects to the gate of the external N-channel MOSFET.
9 VREG power_out Internal drive supply voltage that requires a bypass capacitor to ground (0.47µF to 4.7µF recommended) and must not be biased with an external power source.
10 IN power_in Power supply input, with a recommended operating supply voltage range of 2.97V to 40V.
