Digital DC/DC PMBus 10A Power Module
ZL9010M
The ZL9010M is a 10A variable output, step-down
PMBus-compliant digital power supply. Included in the module
is a high-performance digital PWM controller, power MOSFETs,
an inductor, and all the passive components required for a
highly integrated DC/DC power solution. This power module
has built-in auto-compensation algorithms, which eliminates
the need for manual compensation design work. The
ZL9010M operates over a wide input voltage range and
supports an output voltage range of 0.6V to 3.6V, which can be
set by external resistors or via PMBus. Only bulk input and
output capacitors are needed to finish the design. The output
voltage can be precisely regulated to as low as 0.6V with ±1%
output voltage regulation over line, load, and temperature
variations.
The ZL9010M functions as a switch mode power supply with
added benefits of auto compensation, programmable power
management features, parametric monitoring, and status
reporting capabilities.
The ZL9010M is packaged in a thermally enhanced, compact
(17.2mm x 11.45mm) and low profile (2.5mm) over-molded
high-density array (HDA) package module suitable for
automated assembly by standard surface mount equipment.
The ZL9010M is Pb-free and RoHS compliant.
Figure 1 represents a typical implementation of the ZL9010M.
For PMBus operation, it is recommended to tie the Enable pin
(EN) to SGND.

DESCRIPTION
Internal 2.5V reference. It is used to power internal circuitry.
Power-good output. Provide open-drain power-good signal. By default, the PG pin asserts if the output is within
+15/-10% of the target voltage. These limits and the polarity of the pin may be changed via the I
2
C/PMbus interface.
Enable input. This pin is factory set as active high. Pull-up to enable the module switching and pull-down to disable
switching. If the module is controlled through PMbus command, tie a 10kΩ resistor from this pin to SGND to avoid this
pin floating.
Digital-DC bus (open drain). The DDC pin on all Digital modules in one application should be connected together. This
dedicated bus provides the communication channel between modules for features such as sequencing, fault spreading,
and current sharing.
External temperature sensor input. Connect to an external 2N3904 transistor with a diode configuration. See
Figure 25
on page 24.
Controller input voltage. Tie to VIN directly.
Signal ground. Connect to low impedance ground plane.
Digital ground. Common return for digital signals. Connect to low impedance ground plane.
Clock synchronization. Used for synchronization to external frequency reference.
Serial address select pin. Used to assign unique PMbus address to each module and phase spreading.
Power ground. Connect to low impedance ground plane.

DESCRIPTION
Mode Setting. Used to set the single-phase/current sharing mode, auto-compensation, and SYNC configuration. See
Table 9 on page 19.
Output voltage selection pin. It is used to program the output voltage through pin-strap setting or connecting a resistor from
the V1 pin to SGND.
See “SINGLE RESISTOR VOUT SETTING” on page 15.
The set voltage on this pin is the maximum
allowed output voltage in I
2
C/PMbus programming.
Soft-start pin. Set SS pin by pin-strapping or connecting a resistor to SGND using the appropriate resistor. The pin can
program the delay from when EN is asserted until the output voltage starts to ramp, the output voltage ramp time during
turn on/off, and input undervoltage lockout (UVLO) level (see Table on page 17). This pin can also set tracking ratio and
upper track limit (see Table 10 on page 21).
Tracking sense input. Used to track an external voltage source.
Output voltage positive feedback. Positive inputs of differential remote sense for the regulator. Connect to the output
rail or the regulation point of load/processor.
Output voltage negative feedback. Negative input of the differential remote sense for the regulator. Connect to the
negative rail or ground of the load/processor.
Test pin. For factory test use. Solder down the pin for mechanical strength, but do not connect the pin.
Power inputs. Input voltage range: 4.5V to 13.2V. Tie directly to the input rail. When the input is between 4.5V to 5.5V,
VIN should be tied directly to VCC.
Power ground. Power ground pins for both input and output returns.
Signal ground. Connect to low impedance ground plane (see
Figure 26
on page 25).
Switch node. Use for monitoring switching frequency. SW pad should be floating or used for snubber connections. To
achieve better thermal performance, the SW planes can also be used for heat removal with thermal vias connected to
large inner layers (see
Figure 26
on page 25).
Power Output. Apply output load between these pins and PGND pins. Output voltage range: 0.6V to 3.6V.
