MAX15048/MAX15049
Triple-Output Buck Controllers
with Tracking/Sequencing
MAX15049 Output-Voltage
Sequencing (EN_)
In Figure 1c, when sequencing, the enable input must be
above 0.6V for each PWM controller to start. The V OUT_
outputs and EN_ inputs can be daisy-chained to gener-
ate power sequencing. See Figure 2 and the Typical
Operating Characteristics (V OUT_ to EN_ Sequencing).
Alternately, connect a resistive voltage-divider from the
voltage to be sequenced from the enable input to SGND
to set when each controller should start.
Error Amplifier
The output of the internal transconductance error ampli-
fier (COMP_) is provided for frequency compensation
(see the Compensation Design Guidelines section). FB_
is the inverting input and COMP_ is the output of the error
amplifier. The error transamplifier has an 80dB open-
loop gain and a 10MHz GBW product. See the Typical
Operating Characteristics for a plot of gain and phase
vs. frequency.
Output Short-Circuit
Protection (Hiccup Mode)
The current-limit circuit employs a valley current-limiting
algorithm that uses the synchronous MOSFET’s on-
resistance as the current-sensing element. The current-
limit threshold is internally set at 69mV (typ). Once the
high-side MOSFET turns off, the voltage across the
current-sensing element is monitored. If this voltage
does not exceed the current-limit threshold, the high-
side MOSFET turns on normally at the start of the next
cycle. If the voltage exceeds the current-limit threshold
