Part Number:LP8860-Q1

In my application we use 45V or more to light up 4 separate strings of LEDs , and I'm not able to make them to light up when Adaptative Boost Mode is enabled 

Here follows the registers I'm writing  
 
0x60, 0xED
 0x61, 0xDF
0x62, 0xDC
 0x63, 0xF0
 0x64, 0xDF
0x65, 0xE5
 0x66, 0xF2
 0x67, 0x77
 0x68, 0x77
0x69, 0x71
 0x6A, 0x3F
0x6B, 0xB7
0x6C, 0x17
 0x6D, 0xEF
 0x6E, 0xB0
 0x6F, 0x0B
 0x70, 0xC1
 0x71, 0x77
 0x72, 0xF5
 0x73, 0xFF
 0x74, 0x35
 0x75, 0x06
 0x76, 0xDE
 0x77, 0x88
 0x78, 0x3E

Any ideas why it is failing ?
