MAX1595EUA33+

Analog Devices Inc Maxim Integrated · DC-DC Converters · MSOP-8

MAX1595EUA33+ from Analog Devices Inc Maxim Integrated, in a MSOP-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 AOUT input Analog power and sense input for the error amplifier/comparator; connect to OUT at the output filter capacitor.
2 SHDN input Shutdown input: driving SHDN low turns the device off and disconnects OUT from IN, and driving it high activates the device; SHDN to PGND is rated -0.3V to +6V.
3 IN power_in Input supply, which can range from 1.8V to 5.5V; bypass to GND with a 1µF capacitor.
4 GND power_in Ground reference for the device; PGND to GND is limited to -0.3V to +0.3V.
5 PGND power_in Power ground; connect to GND through a short, low-impedance trace.
6 CXN passive Negative terminal of the charge-pump transfer capacitor (CX); CXN to PGND is limited to -0.3V to the lower of IN + 0.8V or 6.3V.
7 CXP passive Positive terminal of the charge-pump transfer capacitor (CX); CXP to GND is limited to -0.8V to the higher of OUT + 0.8V or IN + 0.8V, but not greater than 6V.
8 OUT power_out Regulated 3.3V or 5V output, bypassed to GND with the output filter capacitor; continuous output current is rated at 150mA maximum.
