ZL6100
high-side MOSFET. for more details, see “High-side Driver
In general, the size of components L1 and C OUT as well as
the overall efficiency of the circuit are inversely proportional
to the switching frequency, f SW . Therefore, the highest
efficiency circuit may be realized by switching the MOSFETs
at the lowest possible frequency; however, this will result in
the largest component size. Conversely, the smallest
possible footprint may be realized by switching at the fastest
possible frequency but this gives a somewhat lower
efficiency. Each user should determine the optimal
combination of size and efficiency when determining the
switching frequency for each application.
The block diagram for the ZL6100 is illustrated in “Typical
voltage is regulated by connecting the differential VSEN pins
directly to the output regulation point. The VSEN signal is
then compared to a reference voltage that has been set to
the desired output voltage level by the user. The error signal
derived from this comparison is converted to a digital value
Multi-mode Pins
In order to simplify circuit design, the ZL6100 incorporates
patented multi-mode pins that allow the user to easily
configure many aspects of the device with no programming.
Most power management features can be configured using
these pins. The multi-mode pins can respond to four different
connections as shown in Table 1. These pins are sampled
when power is applied or by issuing a PMBus Restore
command (see Application Note AN2033).
PIN-STRAP SETTINGS
This is the simplest implementation method, as no external
components are required. Using this method, each pin can
take on one of three possible states: LOW, OPEN, or HIGH.
These pins can be connected to the V25 pin for logic HIGH
settings as this pin provides a regulated voltage higher than
2V. Using a single pin, one of three settings can be selected.
Using two pins, one of nine settings can be selected.
MULTI-MODE PIN CONFIGURATION

with a low-resolution, analog-to-digital (A/D) converter. The
digital signal is applied to an adjustable digital compensation
filter, and the compensated signal is used to derive the
appropriate PWM duty cycle for driving the external
MOSFETs in a way that produces the desired output.
The ZL6100 has several features to improve the power
conversion efficiency. A non-linear response (NLR) loop
improves the response time and reduces the output
deviation as a result of a load transient. The ZL6100

Power Management Overview
The ZL6100 incorporates a wide range of configurable power
management features that are simple to implement with no
external components. Additionally, the ZL6100 includes circuit
protection features that continuously safeguard the device
and load from damage due to unexpected system faults. The
ZL6100 can continuously monitor input voltage, output
voltage/current, internal temperature, and the temperature of
an external thermal diode. A Power-Good output signal is also
included to enable power-on reset functionality for an external
processor.
All power management functions can be configured using
either pin configuration techniques (see Figure 6) or via the
I 2 C/SMBus interface. Monitoring parameters can also be
pre-configured to provide alerts for specific conditions. See
Application Note AN2033 for more details on SMBus
monitoring.

RESISTOR SETTINGS
This method allows a greater range of adjustability when
connecting a finite value resistor (in a specified range)
between the multi-mode pin and SGND. Standard 1%
resistor values are used, and only every fourth E96 resistor
value is used so the device can reliably recognize the value
of resistance connected to the pin while eliminating the error
associated with the resistor accuracy. Up to 31 unique
selections are available using a single resistor.
I 2 C/SMBUS METHOD
Almost any ZL6100 function can be configured via the
I 2 C/SMBus interface using standard PMBus commands.
Additionally, any value that has been configured using the
pin-strap or resistor setting methods can also be re-configured
and/or verified via the I 2 C/SMBus. See Application Note
AN2033 for more details.
