XC9216A33CMR

The XC9216A33CMR is one member of the XC9216 series.It is designed as the group of synchronous-rectification type DC/DC converters with a built-in 0.6 P-channel driver transistor and 0.7 N-channel switching transistor,designed to allow the use of ceramic capacitors.The ICs enable a high efficiency,stable power supply with an output current of 500 mA to be configured using only a coil and two capacitors connected externally.Minimum operating voltage is 2.0 V.Output voltage is internally programmable in a range from 0.9V to 4.0V in increments of 0.1V.

Features of the XC9216A33CMR are:(1)synchronous step-down DC/DC;(2)high efficiency:92%;(3)low ripple rejection:10 mV;(4)output current:500 mA;(5)oscillation frequency:600 kHz,1.2MHz;(6)PWM fixed control:(XC9215 series);(7)maximum duty ratio:100%;(8)ceramic capacitor compatible;(9)ultra small package:SOT-25,USP-6B.The XC9216A33CMR can be used in mobile phones (such as PDC, GSM, CDMA, IMT200 etc.),bluetooth equipment,PDAs,portable communication modem,portable games,cameras,digital cameras and cordless phones,notebook computers.

The absolute maximum ratings of the XC9216A33CMR can be summarized as:(1)VIN pin voltage:-0.3 to 6.5 V ;(2)Lx pin voltage:-0.3 to VIN+0.3 V;(3)VOUT pin voltage:-0.3 to 6.5 V ;(4)CE/MODE pin voltage:-0.3 to VIN+0.3 V;(5)Lx pin current:+/-1000 mA;(6)operating temperature range:-40 to +85;(7)storage temperature range:-55 to +125.If you want to know more information such as the electrical characteristics about the XC9216A33CMR,please download the datasheet in www.seekic.com .
