YB1109MB
YB1109MB is Boost Converter manufactured by YuCan.
- Part of the YB1109M comparator family.
- Part of the YB1109M comparator family.
Description
The YB1109M/YB1109MB is a high efficiency current-mode boost converter with a fixed operation frequency. The YB1109M /YB1109MB hasbeen integrated a very low Rds-on NMOSFTET to reduce power loss and achieve high efficiency. The maximum efficiency is up to 93%. YB1109M/YB1109MB can output 2A current when VIN is higher than 3.3V and output is 5V. 1.2MHz operation frequency minimizes L and C value, and internal pensation network reduces external ponent counts. SOT23-6 package provides the best solution for PCB layout area.

Pin Name 1 2 3
Symbol SW VIN GND
Pin Function
Power switch output. Connect the inductor and the blocking Schottky diode to SW.
Feedback
Enable pin. A high input at EN enables the device
EN and a low input disables the devices. When not used, connect EN to the input source for automatic startup.
VIN Input supply pin. Must be locally bypassed.
No Internal Connection
