Operating Junction Temperature TJ refer to „Thermal Derating“ -40°C +125°C Thermal Resistance (8) RthJA junction to ambient 17K/W RthJC junction to case 3.4K/W OUTPUT VOLTAGE SETTING The RPH-3.0 series offers the feature of trimming the output voltage by using external trim resistors (see „Typical Application“). The external resistor divider is used to set the output voltage. The feedback resistor (R FB1) cannot be too large or too small considering the trade-off for stability and dynamics. There is no strict requirement for the feedback resistor. RFB2 can be calculated with equation below. The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary.

Use wide traces to connect OUT. 29 VDD Power for internal MOSFET driver and BST charging circuit. 31 PG Power good indication. Connect a resistor from PG to a pull-up power source if it is being used. 32 SS Soft start. Float SS for a default 1.2ms SS time. The SS time can be extended by connecting an external capacitor between SS and AGND. 33-35 GND Ground for internal logic and signal circuit. 36 COMP Compensation networks setting. Connect an external resistor series with a capacitor between COMP and AGND. 37 FB Feedback. FB is the input to the PWM comparator. Connect an external resistor divider between the output and AGND. 39 FREQ Frequency set pin. Connect a resistor from FREQ to ground to set the switching frequency. If an external SYNC clock is applied to FREQ, the converter follows this SYNC clock frequency.

40 CTRL

Enable input. Pull CTRL below the specified threshold to shut down the chip. There is no internal pull-up or pull-down circuit, so CTRL cannot be floated. CTRL is a pin that turns the module on and off. Drive CTRL above 1.6V to turn on the regulator. Drive CTRL below 1.3V to turn off the regulator.
