PIN FUNCTION
PIN NAME DESCRIPTION
1 Vs Common suppy connection also Drain of the power DMOS.
2 BS A capacitor connected between this pin and the Source of the power DMOS pin Out
gives the possibility to bootstrap the gate driving voltage of the power DMOS.
3 OSC A capacitance CT connected between GND and this terminal determines the PWM
switching frequency.
4 GND Common ground connection.
5 PRO A resistor connected between this pin and GND provide the possibility to programming
the output voltage slew rate, the PWM oscillator frequency and the short current value.
6 IN Analog input for controlling the PWM ratio, related to Vs.
7 OUT Source connection of the internal power DMOS.
