13 / 26 page ![]() 2021-2022 Microchip Technology Inc. and its subsidiaries DS20006489B-page 13 MIC23153 3.0 PIN DESCRIPTIONS The descriptions of the pins are listed in Table 3-1. TABLE 3-1: PIN FUNCTION TABLE Pin Number (Fixed) Pin Number (Adjustable) Pin Name Description 1 1 SW Switch (Output): Internal power MOSFET output switches. 2 2 EN Enable (Input): Logic high enables operation of the regulator. Logic low will shut down the device. Do not leave floating. 3 3 SNS Sense: Connect to VOUT as close to output capacitor as possible to sense output voltage. 4 — NC Not Internally Connected. — 4 FB Feedback: Connect a resistor divider from the output to ground to set the output voltage. 5 5 PG Power Good: Open-drain output for the power good indicator. Use a pull-up resistor from this pin to a voltage source to detect a power good condition. 6 6 SS Soft-Start: Place a capacitor from this pin to ground to program the soft start time. Do not leave floating, 100 pF minimum CSS is required. 7 7 AGND Analog Ground: Connect to central ground point where all high current paths meet (CIN, COUT, PGND) for best operation. 8, 9 8, 9 VIN Input Voltage: Connect a capacitor to ground to decouple the noise. 10 10 PGND Power Ground. |
