Complete High Efficiency DC/DC Power Module
ISL8204M, ISL8206M
The ISL8204M, ISL8206M is a family of pin-compatible power
modules to the ISL8201M. These are simple and easy to use,
high power DC/DC modules and are ideal for a wide variety of
applications. The ISL820xM family of high current DC/DC
step-down modules virtually eliminate design and manufacturing
risks while dramatically improving time to market.
The simplicity is in the family's "Off The Shelf" unassisted
implementation. All you need is the ISL820xM for the current
requirement of your design, bulk input and output capacitors and
one resistor, to program the output voltage, and you have a
complete high current power design ready for your market.
This family of buck converters is packaged in a thermally
enhanced compact (15mmx15mm) overmolded QFN Package
that operates without a heatsink, even at full load over
temperature. The package supports simple, reliable, automated
assembly using standard surface mount equipment while
making it easy to probe to all pins. The lack of a required heat
dissipation layer, provides easy access to all pins and the limited
number of the external components reduce the PCB to a
component layer and a simple ground layer.
Additionally, each IC in the family is footprint compatible, making
it easy to change your design to meet different power needs
without changing your layout. One simple layout fits all.

DESCRIPTION
Power ground pin for signal, input, and output return path. PGND needs to connect to one (or more) ground plane(s)
immediately, which is recommended to minimize the effect of switching noise, copper losses, and maximize heat
dissipation. Range: 0V.
This pin provides the bias supply for ISL8204M, ISL8206M, as well as the low-side MOSFET’s gate and high-side
MOSFET’s gate. If PVCC rises above 6.5V, an internal 5V regulator will supply to the internal logics bias (but high-side
and low-side MOSFET gate will still be sourced by PVCC). Connect a well decoupled +5V or +12V supply to this pin.
Connect 1µF ceramic capacitor to ground plane directly. Range: 4.5V to 14.4V.
No internal connection.
The ISET pin is the input for the overcurrent protection (OCP) setting, which compares the rDS(ON) of the low-side
MOSFET to set the overcurrent threshold. The ISL8204M, ISL8206M has an initial protect overcurrent limit. It has an
integrated internal 4.12k2.87kresistor (RSET-IN) between the ISET and PGND pins, which can prevent significant
overcurrent impact to the module. One can also connect an additional resistor RSET-EX between the ISET pin and the
PGND pin in order to reduce the current limit point by paralleling. Range: 0 to PVCC.
Power input pin. Apply input voltage between the VIN pin and PGND pin. It is recommended to place an input decoupling
capacitor directly between the VIN pin and the PGND pin. The input capacitor should be placed as closely as possible to
the module. Range: 1V to 20V.
The PHASE pin is the switching node between the high and low-side MOSFET. It also returns the current path for the
high-side MOSFET driver and detects the low-side MOSFET drain voltage for the overcurrent limits point. Range: 0V to 30V.
Power ground pin for signal, input, and output return path. PGND needs to connect to one (or more) ground plane(s)
immediately, which is recommended to minimize the effect of switching noise, copper losses, and maximize heat
dissipation. Range: 0V.
Power output pin. Apply output load between this pin and the PGND pin. It is recommended to place a high frequency
output decoupling capacitor directly between the VOUT pin and the PGND pin. The output capacitor should be placed as
closely as possible to the module. Range: 0.6V to 6V.
