ISB (Integrated System in Board): original SiP(System in Package) technology

Super thin and small 1ch DC/DC converter IC SR Series

[Features and Functions]
  • Size 3.4×3.4×0.75mm³ / 3.09×2.8×0.75mm³
  • It is advantageous for efficiency and the characteristic such as the output ripples because it is possible to wire by the beeline between parts and parts. Moreover, the mounting area can be decreased compared with the discrete part composition.
  • Controllable Output voltage by external resistance.
  • Built-in stand-by function.
  • PWM/PFM Automatic Switching Control or Manual Switching Control
  • Oscillation Frequency: 100kHz, 180kHz, 300kHz, 500kHz

*We recommend that the maximum value of the output voltage is less than 1/1.5 times VDSS and VRRM.

Moreover, please confirm each rated voltage is not exceeded in actual use.
