Sipex’s PowerBloxTM Family offers high voltage capability in an ultra-small package!
Applications Include:
Easy to Use
Ultra-Miniature
Power Up Protocols
Sipex developed PowerBlox to enable
designers to create a quick and easy power
system with the fewest number of external
size
components. This family of high current,
Actual
4mm
high voltage, ultra-miniature DC/DC buck
7mm x
regulators greatly simplifies the complex
task of designing power solutions for next
generation electronics applications.
• Sipex's unique package technology
produces the industry’s smallest 8A
component, measuring a mere
7mm x 4mm.
By offering various power up protocols,
Sipex PowerBlox ICs eliminate the use of
sequencing control ICs, simplifying system
design and reducing costs. Depending on
your design requirements, you can choose
simultaneous, sequential or ratiometric power
up, using a proprietary chip-to-chip interface.
• The part is packaged in a custom
DFN package with three integrated
heat sinks for outstanding thermal
management.
High Efficiency
Simultaneous Power Up
• With integrated high performance, low
resistance MOSFETs, the PowerBlox family
achieves up to 95% efficiency, surpassing
all competing solutions.
• Cable Modems
• Industrial Applications
• Set Top Boxes
• DC to DC Power
Supplies
• Plasma TVs
• Medical
• LCD Monitors
• FPGA Power Supplies
• Robotics
• Automated Test
Equipment
• Routers
• DataCom Equipment
All converters begin their soft start cycle simultaneously, with the same slew rate.

• Even at high load, the family is able to
maintain an impressive level of efficiency,
thus minimizing heat dissipation and energy
loss.

In sequential power up, VOUT1 powers up first and then triggers VOUT2 which powers
up and then triggers VOUT3.
Sequential Power Up
• Sipex’s PowerBlox family delivers from 3A
to 12A output current and supports a very
wide input voltage range of 2.5V – 28V.
• These parts offer the world’s only high
current synchronous buck regulators with
support for input voltages greater than 6V.
• Offered in frequencies ranging from 300kHz
to 1.3MHz, PowerBlox ICs support a wide
variety of applications.
