Evaluation board available. NX2113/2113A 300kHz & 600kHz SYNCHRONOUS PWM CONTROLLER WITH PROGRAMMABLE BUS UVLO PRELIMINARY DATA SHEET Pb Free Product DESCRIPTION Synchronous Controller in 10 Pin Package The NX2113 controller IC is a synchronous Buck conBus voltage operation from 2V to 25V troller IC designed for step down DC to DC converter Enable pin allows programmable BUS UVLO applications. Synchronous control operation replaces the Less than 50 nS adaptive deadband traditional catch diode with an Nch MOSFET resulting Internal 300kHz for 2113 and 600kHz for 2113A in improved converter efficiency. The NX2113 controller Internal Digital Soft Start Function is optimized to convert bus voltages from 2V to 25V to Separated power ground and analog ground for outputs as low as 0.8V voltage using Enable pin to extra noise filtering program the BUS voltage start up threshold. The NX2113 n Pb-free and RoHS compliant operates at 300kHz while 2113A is set at 600kHz operation which together with less than 50 nS of dead band provides an efficient and cost effective solution. n Graphic Card on board converters Other features of the device are: n Memory Vcore or Vddq supply Internal digital soft start; Vcc undervoltage lock out; n On board DC to DC such as Output undervoltage protection with digital filter and shut12V, 5V to 3.3V, 2.5V or 1.8V down capability via the enable pin. n Hard Disk Drive L2 1uH C3 47uF R3 10 R5 68k C4 1uF 7 n n n n n n n FEATURES APPLICATIONS TYPICAL APPLICATION Vin +12V C5 1uF C6 1uF Cin 270uF,18mohm Vin +5V D1 6 5 1 2 Vcc PVcc BST C7 0.1uF M1 L1 1.5uH OFF ON R8 10k 2N3904 R7 10k C9 1uF R6 12.4k C1 47pF C2 2.7nF R4 11k NX2113A EN Comp Hdrv SW Ldrv 9 10 8 Fb PGnd Gnd 3 11 4 M2 Co 3x (220uF,12mohm) Vout +1.6V,10A R2 10k 1% R1 10k 1% R9 1.2k C8 2.2nF Figure1 - Typical application of 2113A ORDERING INFORMATION Device NX2113CMTR NX2113CUTR NX2113ACMTR NX2113ACUTR Rev. 2.0 11/18/05 Temperature 0 to 70oC 0 to 70o C 0 to 70oC 0 to 70o C Package MLPD-10L MSOP-10L MLPD-10L MSOP-10L Frequency 300kHz 300kHz 600kHz 600kHz Pb-Free Yes Yes Yes Yes 1 NX2113/2113A ABSOLUTE MAXIMUM RATINGS Vcc to GND & BST to SW voltage ................... 6.5V BST to GND Voltage ...................................... 35V Storage Temperature Range ............................. -65oC to 150oC Operating Junction Temperature Range ............. -40oC to 125oC CAUTION: Stresses above those listed in "ABSOLUTE MAXIMUM RATINGS", may cause permanent damage to the device.
