MBD9G101G-TR

MSKSEMI · DC-DC Converters · SOT-23-6

MBD9G101G-TR 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 BST passive Bootstrap pin. A capacitor connected between SW and BST forms a floating supply for the high-side switch driver. BST voltage rating: (Vsw-0.3) to (Vsw+5V).
2 GND power_in Ground reference pin for the device. Connect to the system ground plane.
3 FB input Adjustable version feedback input. Connect FB to the center point of the external resistor divider from VOUT to GND. Internal feedback reference is 0.795 V typical; FB absolute maximum -0.3 V to 6 V.
4 EN input Enable input. Drive to a logic-high (rising threshold 3.0 V typ) to enable the IC. Drive to a logic-low (falling threshold 0.6 V typ) to disable the IC and enter micro-power shutdown mode. Absolute maximum -0.3 V to 50 V.
5 IN power_in Power supply input pin. Operating range 4.5 V to 50 V (55 V max operating, 60 V transient). Bypass close to pin with a low-ESR ceramic capacitor (recommended 22 uF + 0.1 uF).
6 SW output Switching node. Internal high-side power MOSFET drain (900 mΩ RDS(ON)); connect to the external inductor and freewheel/Schottky diode. SW voltage rating -0.3 V to (VIN + 0.5 V).
