To avoid device shutdown by video light safety timeout, MODE_CTRL[1:0] bits need to be refreshed within less than 13.0s. Writing to REGISTER2[6:5] automatically updates REGISTER1[6:5]. ENVM Enable Voltage Mode bit. 0: Normal operation. 1: Forces the device into a constant voltage source. In read mode, the ENVM bit is automatically updated to reflect the logic state of the ENVM input pin. FC13[4:0] Flash Current Control bits (LED1/3). 00000: 0mA.(1) (2) 00001: 25mA 00010: 50mA 00011: 75mA 00100: 100mA 00101: 125mA 00110: 150mA 00111: 175mA 01000: 200mA 01001: 225mA 01010: 250mA 01011: 275mA 01100: 300mA 01101: 325mA 01110: 350mA 01111: 375mA 10000 ... 11111: 400mA (1) LEDs are off, VOUT set according to OV[3:0]. (2) When FC13[4:0] and FC2[5:0] are both reset, the device operates in voltage regulation mode. The output voltage is set according to OV[3:0]. 34 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated Product Folder Link(s): TPS61310 |
