MAX1836EUT50+T

Analog Devices Inc Maxim Integrated · DC-DC Converters · SOT-23-6

MAX1836EUT50+T from Analog Devices Inc Maxim Integrated, in a SOT-23-6. 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 FB input Dual-mode feedback input: connect to GND for the preset 5.0V output, or to a resistive divider from the output to set 1.25V to VIN with OUT connected to GND.
2 GND power_in Ground reference for the device.
3 IN power_in Input voltage with a 4.5V to 24V input range; connected to the internal p-channel power MOSFET source.
4 LX output Inductor connection to the internal p-channel power MOSFET drain; LX is high impedance in shutdown.
5 SHDN input Shutdown input: a logic-low shuts down the device and reduces supply current to 3µA, connect to IN for normal operation, and the input slew rate must exceed 10V/ms.
6 OUT input Regulated output high-impedance sense input: connect to the output for the preset voltage, or to GND when using an external resistive divider.
