NXP DC6M401X6-18S Small, highly efficient switching converter Datasheet

DC6M4/5/6 series
6 MHz DC/DC
step-down converter
Small, highly efficient switching converters
with ultra-low output voltage ripple
Ideal for mobile and battery driven devices, the DC6M4/5/6 series combine the advantages of a high
frequency DC/DC buck converter with high performance and small package (1.0 mm * 1.4 mm). The
6 MHz switching frequency allows use of inductors as small as 470 nH to save board space. Another
key advantage is the ultra-low output voltage ripple performance of only 7 mV (typ).
Key features
`` Ultra-low output voltage ripple of 7 mV (typ)
`` Very small WLCSP6 package for board space reduction
`` Optimized for load range of 40 mA to 650 mA with an efficiency of up to 95%
`` Input voltage range 2.3 V - 5.5 V
`` Available with output currents of 425, 500, 650 mA
`` Low quiescent current of 0.2 µA (typ) in shutdown
`` Inrush, short circuit & temperature protection
`` Available with Auto/PWM mode select, output voltage `
select or power good/XSHUTDOWN option

Ultra-low output voltage ripple performance
Key applications
`` Mobile phones
`` PC tablets
`` DSCs (Digital Still Cameras)
`` Video cameras
`` Game pads
`` Notebooks, Netbooks, and Ultrabooks

Three different operation mode versions can be ordered:
`` DC6Mx01 - Modulation select: automatic pulse frequency modulation (PFM) / pulse width modulation (PWM) or forced PWM
mode operation. Selection via the A1 MODE pin.
`` DC6Mx02 - Output voltage select: switch between 2 different output voltages VOUT, e.g. /1218 means 1.2 V or 1.8 V to be
selected via the A1 MODE pin.
`` DC6Mx03 – Power good/XSHUTDOWN output: e.g. enabling a camera device through the A1 pin.
