MYRBP330080B21RE

MYRBP330080B21RE is a MYRBP series, PicoBK™ synchronous step-up mini DC/DC converter. A stable step-up power supply is configured using only two capacitors connected externally. An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the circuit wiring. A wide operating voltage range of 0.65V to 6.0V enables support for applications that require an internally fixed output voltage (2.2V to 5.5V). It is used in applications such as portable equipment, beauty, and health equipment, wearable devices, game and hobby, PC peripherals, and devices with 1~3 alkaline, 1~3 nickel hydride, 1 lithium, and 1 Li-ion.
