Bit Description

sd3_fast

RW_SS

Selects a faster regulation mode for SD3 suitable

for larger load changes.

0 : normal mode, Cout (according spec)

1 : fast mode, 2 x Cout (according spec) required

sd3_force_pwm

Selects force pwm mode

0 : normal mode

1 : force pwm, inverted coil current possible to

keep the fixed frequency

sd3_low_noise

Enables low noise mode of SD3. If enabled smaller

current pulses and output ripple is activated

0 : Normal mode. Minimum current pulses of about

10% the current limit are applied in skip mode

1 : Low noise mode. Only minimum on time

applied in skip mode

sd2_fast

RW_SS
