PI354x-00
36V_IN to 60V_IN Cool-Power ZVS Buck Regulator & LED Driver
Product Description
The PI354x-00 is a family of high input voltage, wide input
range DC-DC ZVS-Buck regulators integrating controller, power
switches, and support components all within a high density
System-in-Package (SiP). The PI354x-00 products are designed
to operate within an SELV compliant system with steady state
operation limited to 60V. The PI354x-00 products allow for
transient voltage conditions up to 70V before shutdown is
triggered. The integration of a high-performance Zero-Voltage
Switching (ZVS) topology, within the PI354x-00 series, increases
point of load performance providing best in class power
efficiency. The PI354x-00 requires only an external inductor,
two voltage selection resistors and minimal capacitors to form a
complete DC-DC switching mode buck regulator.
