ME2185ASPG

MICRONE · DC-DC Converters · ESOP-8

ME2185ASPG from MICRONE, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 PGND power_in Power ground pin of the power switches.
2 PGND power_in Power ground pin of the power switches.
3 EN input Enable pin: high (min 0.9V) powers on for normal operation, low (max 0.2V) powers off to standby with shutdown current max 1.0uA.
4 Ilimit passive Current limit setting pin; an external resistor RCS sets the inductor peak current limit (e.g. 30K gives 4.30A at VIN=3.3V).
5 AGND power_in Analog ground.
6 ADJ input Feedback voltage pin with 1.25V typ. (1.225V to 1.275V) reference, connected to the output divider R1/R2.
7 AVDD power_in IC analog power supply pin, input range 2.9V to 4.4V, absolute max 6.0V.
8 PVDD power_in IC power supply pin, input range 2.9V to 4.4V, absolute max 6.0V.
9 LX passive Power switching pin connected to the inductor; voltage rating -0.3V to VDD+0.3V (exposed pad of the ESOP8).
