“PicoBK™” MYRGP-W／MYRGP-B series

1.0A Inductor Built-in Step-Down DC/DC Converters

☆GreenOperationCompatible

■GENERAL DESCRIPTION

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

which integrates an inductor and a control IC in one tiny package (2.0mm×2.5mm, 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 2.5V to 5.5V enables

support for applications that require an internally fixed output voltage (0.8V to 3.6V).

The MYRGP-W/MYRGP-B series use synchronous rectification at an operating frequency

of 3.0MHz. The MYRGP-W/MYRGP-B series use High Speed Transient Response -COT

synchronous rectification.

PWM control (MYRGP-W) or PWM/PFM switching control (MYRGP-B) automatic 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 forcedOFF when input voltagebecomes 2.0V or lower. WhenCE=Low,

the integrated C_Ldischarge function which enables the electric chargeat the outputcapacitor C_Lto be dischargedvia the internal

discharge switch located between the L_Xand V_SSpins. The power consumption will be less than 1.0μA.
