GENERAL DESCRIPTION  
The MYRGM-W/MYRGM-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×3.2mm, h=1.0mm).  
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 2.7V to 5.5V enables  
Support for applications that require an internally fixed output voltage (0.8V to 3.6V).  
The MYRGM-W/MYRGM-B series use synchronous rectification at an operating frequency  
of 3.0MHz. The MYRGM-W/MYRGM-B series use High Speed Transient Response-COT.  
PWM control (MYRGM-W) or automatic PWM/PFM switching control (MYRGM-B) can be selected.  
The series have a high speed soft-start as fast as 0.3ms in typical for quick turn-on. With the built-in UVLO (Under Voltage Lock  
Out) function, the internal P-channel driver transistor is forced OFF when input voltage becomes 2.0V or lower. When  
CE=Low, the integrated CL discharge function which enables the electric charge at the output capacitor CL to be discharged via  
the internal discharge switch located between the LX and VSS pins. The power consumption will be less than 1.0μA.
