VALUE
Control the RAMP Timing
B7 (MSB)
000 = 32mV/μs
001 = 16mV/μs
010 = 8mV/μs
B6
RAMP[2:0]
011 = 4mV/μs
000
100 = 2mV/μs
101 = 1mV/μs
B5
110 = 0.5mV/μs
111 = 0.25mV/μs
Only Valid When Converter is Operating in OPERATION_MODE 0
0 = Automatically change between power-save mode and PWM mode,
B4
FORCE_HYS
depending on load current.
1 = Converter always operates in power-save mode regardless of load
0
current as long as OPERATION_MODE = 0. If OPERATION_MODE =
1, this setting is ignored.
Force Oscillator While Running in Hysteretic Mode
0 = Internal oscillator is disabled in power save when operating in
B3
FORCE_OSC
hysteretic mode.
0
1 = Internal oscillator is enabled in power save even when operating in
hysteretic mode.
B2
Reserved for future use.
0
Active Ramp-Down Control for Power-Save Mode
B1
RAMP_DOWN
0 = Active ramp disabled for power-save mode.
1 = During ramp-down, the error crossing detector is disabled allowing
0
negative current to flow thought the nMOS device.
B0 (LSB)
Reserve for future use.
