PicoBK™ DC/DC Converters

Murata's MYR series DC/DC converters now include 150 mA models with extremely quiescent current (I_Q= 0.2 μA). This product series integrates a coil and a control IC. The ultra-small form-factor measures as small as 2.5 mm x 2.0 mm x 1.0 mm. The MYR series is significantly smaller than discrete solutions. In most cases, these modules occupy less than half the footprint of the same solution implemented with discrete components.

These DC/DC converters achieve high efficiency, low noise, and high heat dissipation, and have input ranges that support both 3.3 V and 5.0 V rails. The typical efficiency of the MYRGP is 93% at 5.0 V_IN / 3.3 V_OUT. The control method can be selected fixed, PWM, or PFM/PWM auto switch. The 2 A parts have adjustable output voltages set with an external resistor. The remaining parts come with fixed output voltages.
