MP1470-MS

MSKSEMI · DC-DC Converters · SOT-23-6

MP1470-MS from MSKSEMI, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Analog ground pin. Return path for internal analog circuitry and the low-side power MOSFET.
2 SW power_out Switching node. Connects to the source of the internal high-side MOSFET and drain of the internal low-side MOSFET; connect the external inductor here. Absolute range -0.3V to (VIN+0.5V).
3 VIN power_in Power supply input pin. 4.5V to 21V operating range (absolute max 22V). Bypass to GND with a low-ESR ceramic capacitor (e.g. 22 µF).
4 FB input Adjustable-output feedback input. Connect FB to the center point of an external resistor divider from VOUT to GND; regulated to 0.800V (typ), 0.776V min / 0.824V max.
5 EN input Enable input. Drive logic-high to enable the IC; drive logic-low to disable and enter micro-power shutdown (~1 µA). For automatic start-up, tie EN to VIN through a 200 kΩ resistor. Absolute max -0.3V to 6V.
6 BS passive Bootstrap pin. A capacitor connected between SW and BS forms a floating supply for the high-side switch driver. Absolute range (Vsw-0.3V) to (Vsw+5V).
