4 / 40 page LM10520 SNVS638 – NOVEMBER 2010 www.ti.com PIN DESCRIPTIONS Number Pad Name Type Pad Description DAP GND Connect Die Attach Pad to ground 1 BOOT Analog Boot cap voltage. Connect boot capacitor to this pin. 2 LG Output Low Side MOSFET gate drive. 3 PGND GND Power ground. 4 VCC Power 5V bias input 5 PWGD GND Power good signal 6 ISEN Analog Current limit sense 7 VIN Power High voltage bias input 8 NC No Connect 9 VCC5 Power 5V bias output 10 FLT_N I/O External fault input, active low. Causes output to be disabled and resets R0 (output voltage register) 11 VDD Power Digital circuitry bias 12 ADDR Analog Connect a resistor from this to ground to set the PWI address 13 ENBIAS Input Enable for digital circuitry 14 CONTROL Input Enable for output voltage 15 IOUT1 Analog Connect this pin the FB pin 16 RESET_N Input Digital circuitry reset, active low 17 CNTL_EN Output Digital circuitry output which control Vout enable/disable 18 VPWI Power PWI I/O bias input 19 SPWI I/O PWI signal 20 SCLK Output PWI clock 21 ON/OFF Input Enable for internal 5V LDO 22 EAO Analog Error amp output 23 SS/TRACK Analog Connecting a capacitor to ground will set the softstart time. Optionally, if this pin is driven externally the output will track the voltage at this pin 24 FB Feedback connection 25 FREQ/SYNC Analog Connecting a resistor from this pin to ground will set the switching frequency. Alternatively, a clock source can drive this pin, and the LM10520 will synchronize to the clock frequency. 26 SD Input Shutdown for the analog circuitry 27 PGND GND Power ground 28 HG Analog High side MOSFET drive 4 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Links: LM10520 |
