Revision 1.1.1 / 20060707
16 - 70
7.2.5 Step up Registers
Reg. Control
Addr: 00
This register enables/disables the LDOs, Charge Pumps, Charge Pump LEDs, current
sinks, the Step Up DC/DC Converter
Bit
Bit Name
Default
Access
Description
3
step_up_on
0
R/W
Enable the step up converter
0b = Disable the Step Up DC/DC Converter.
1b = Enable the Step Up DC/DC Converter.
DCDC Control 1
Addr: 21h
This register controls the Step Up DC/DC Converter.
Bit
Bit Name
Default
Access
Description
0
step_up_frequ
0
R/W
Defines the clock frequency of the Step Up DC/DC
Converter.
0 = 1 MHz
1 = 500 kHz
2:1
step_up_fb
00
R/W
Controls the feedback source if step_up_fb_auto = 0
00 = DCDC_FB enabled (external resistor divider).
Set step_up_fb=00 (DCDC_FB), if external
PWM is enabled for CURR1 or CURR2
01 = CURR1 feedback enabled (feedback via white LEDs.
10 = CURR2 feedback enabled (feedback via white LEDs.
11 = Reserved.
7:3
step_up_vtuning
00000
R/W
Defines the tuning current at pin DCDC_FB.
00000 = 0 µA
00001 = 1 µA
00010 = 2 µA
…
10000 = 15 µA
…
11111 = 31 µA
DCDC Control 2
Addr: 22h
This register controls the Step Up DC/DC Converter and low-voltage current sinks
CURR3x.
Bit
Bit Name
Default
Access
Description
0
step_up_res
0
R/W
Gain selection for Step Up DC/DC Converter.
0 = Select 0 if Step Up DC/DC Converter is used with
current feedback (CURR1, CURR2) or if DCDC_FB is
used with current feedback only – only R1, C1
connected
1 = Select 1 if DCDC_FB is used with external resistor
divider (2 resistors).
1
skip_fast
0
R/W
Step Up DC/DC Converter output voltage at low loads, when
pulse skipping is active.
0 = Accurate output voltage, more ripple.
1 = Elevated output voltage, less ripple.
2
stepup_prot
1
R/W
Step Up DC/DC Converter protection.
0 = No overvoltage protection.
1 = Overvoltage protection on pin DCDC_FB enabled
voltage limitation =1.25V on DCDC_FB
