5 Pin Configuration and Functions

GUID-20230303-SS0I-JJJM-5LCQ-NVCCJBFDCPS6-low.svg Figure 5-1 RQS Package,52-Pin VQFN(Top View)
Table 5-1 Pin Functions
PIN TYPE(1) DESCRIPTION
NAME NO.
NC1 1, 16 — Used to anchor QFN package to PCB. Pins must be soldered to PCB landing pads. The PCB landing pads are non-solder mask defined pads and must not be physically connected to any other metal on the PCB. Internally connected to DRAIN.
DRAIN 2–15 P GaN FET drain. Internally connected to NC1.
NC2 17, 27, 43, 47, 52 — Used to anchor QFN package to PCB. Pins must be soldered to PCB landing pads. The PCB landing pads are non-solder mask defined pads and must not be physically connected to any other metal on the PCB. Internally connected to SOURCE, and THERMAL PAD.
SOURCE 18–26, 28–39 P GaN FET source. Internally connected to NC2, and THERMAL PAD.
VNEG 40, 41 P Internal buck-boost converter negative output. Used as the negative supply to turn off the depletion mode GaN FET. Bypass to SOURCE with a 2.2-µF capacitor.
BBSW 42 P Internal buck-boost converter switch pin. Connect an inductor from this point to SOURCE.
VDD 44 P Device input supply.
IN 45 I CMOS-compatible non-inverting input used to turn the FET on and off.
FAULT 46 O Push-pull digital output that asserts low during a fault condition. Refer to Fault Detection for details.
ZVD 48 O Push-pull digital output that provides zero-voltage detection signal to indicate if device achieves zero-voltage switching in current switching cycle. Refer to Section 8.3.11 for details.
TEMP 49 O Push-pull digital output that gives information about the GaN FET temperature. Outputs a fixed 9-kHz pulsed waveform. The device temperature is encoded as the duty cycle of the waveform.
RDRV 50 I Drive-strength selection pin. Connect a resistor from this pin to SOURCE to set the turn-on drive strength to control slew rate. Tie the pin to SOURCE to enable 150 V/ns and tie the pin to LDO5V to enable 100 V/ns.
LDO5V 51 P 5-V LDO output for external digital isolator. If using this externally, connect a 0.1-µF or greater capacitor to SOURCE.
THERMAL PAD — — Thermal pad. Internally connected to SOURCE, and NC2.
