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 Conversion efficiency Ultra-low output voltage ripple performance Key applications `` Mobile phones `` PC tablets `` DSCs (Digital Still Cameras) `` Video cameras `` Game pads `` Notebooks, Netbooks, and Ultrabooks 30 Vripple (mVpp) 25 20 15 VIN = 4.2 V VIN = 3.6 V VIN = 3.0 V 10 5 0 0 100 200 300 400 500 600 IOUT (mA) 700 100 efficiency (%) 80 60 DC6M601X6/285S 40 20 0 0 100 200 300 400 500 600 IOUT (mA) 700 NXPs new DC6M4/5/6 product series are an ideal solution for mobile applications and battery driven devices.
