Pin Configuration VIN 1 10 VOUT 2 VIN 9 VOUT EXP SS 3 8 FLTB EN 4 7 POVP ILIM 5 6 GND DFN3x3-10L(Top Transparent View)Pin DescriptionPin NumberPin NamePin Function 1, 2 VIN Supply input. Connected to internal power regulator. They are internally connected together. 3 SS Soft Start control. Connect a capacitor CSS from SS to GND to set the soft start time. 4 EN Enable input. Active high. 5 ILIM Current limit set pin. Connect a 1% resistor RLIM from ILIM to GND to set the current limit threshold. 6 GND Ground 7 POVP Programmable Over Voltage Protection. Use resistor divider from VIN to GND to set the OVP threshold. 8 FLTB Open-drain Fault indicator. 9, 10 VOUT Power output. Connect to Type C port. They are internally connected together. Exposed Thermal Pad. It must be connected to GND plane for optimal thermal dissipation. Solder EXP EXP to a metal surface directly underneath the EXP and connect to PCB ground on multiple layers through VIAs for multi-layer PCB design. For best thermal performance make the ground copper pads as large as possible and connect to EXP with multiple VIAs. Rev. 1.0 December 2020 www.aosmd.com Page 2 of 18
