■GENERAL DESCRIPTION

The MYRGP-W/B series is a synchronous step-down mini DC/DC converter

which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, H=1.0mm).

A stable power supply with an output current of 600mA is configured using only two capacitors

connected externally. Operating voltage range is from 2.0V to 6.0V.

Output voltage is internally set in a range from 0.8V to 4.0V in increments of 0.05V.

The device is operated by 3.0MHz, and includes 0.42Ω P-channel driver transistor

and 0.52Ω N-channel switching transistor. As for operation mode, the MYRGP-W series is PWM control,

the MYRGP-B series is automatic PWM/PFM switching control.

During stand-by, the device is shutdown to reduce current consumption to as low as 1.0μA or less. With the built-in UVLO (Under Voltage Lock Out) function, the internal driver transistor is forced OFF when input voltage becomes 1.4V or lower.

MYRGP-x-RC integrate CL auto discharge function which enables the electric charge stored at the output capacitor CL to be discharged via the internal auto-discharge switch located between the LX and VSS pins.

When the devices enter stand-by mode, output voltage quickly returns to the VSS level as a result of this function.
