NXP Semiconductors - DC-DC Conv Ultra-Low Output Voltage Ripple - 19 October 2012

State-of-the-art DC6M DC-DC switching regulator family featuring a very high 6-MHz frequency, an ultra-low output voltage ripple performance of 7 mV and high efficiency up to 95%.

  Product page  Datasheet

    The DC6M4, DC6M5 and DC6M6 DC/DC step-down switching regulators provide the following features
  • High 6 MHz switching frequency, which allows the usage of very small inductors (470 nH).
  • Availability in output currents of 425, 500 and 650 mA.
  • Output signal with very low disturbances; output ripple typically at 7 mV.
  • Very high efficiency of up to 95%; optimized for loads from 40 to 650 mA.
  • Ability to disable the device, which reduces the quiescent current down to 0.2 microA.
  • Input voltage range from 2.3 to 5.5 V, and an output voltage range from 1.2 to 2.85 V.
  • Very small WLCSP6 package (1.36 x 0.96 x 0.47 mm)
  • High power dissipation of 800 mW
  • Many additional options, including voltage switch; a forced PWM mode for Pulse Width Modulation (instead of automatic Pulse Frequency Modulation/PWM switch); or the SMIA standard (XSHUTDOWN/powergood) option.

  • Application
  • Battery-operated devices requiring high-efficiency step-down voltage conversion.
