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 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 C L discharge function which enables the electric charge at the output capacitor C L to be discharged via the internal discharge switch located between the L X and V SS pins. The power consumption will be less than 1.0μA
