pah350s48 TDK Corp., pah350s48 Datasheet - Page 3

• Manufacturer Part Number: pah350s48
• Description: Compact And High-power Dc/dc Power-module
• Manufacturer: TDK Corp.

Power supplies with high power (450W) and
high efficiency (92%) support transmission
amplifiers for next-generation cell phones.
High efficiency:
92% - top level in the industry
PAH450S48 achieves a 3% improvement on
efficiency against our previous half-brick sized
product (PAH350S48)! It even achieves a 2%
improvement compared with our previous
product (PAF500F48) with 48Vin and similar
output capacity.
Compact & high density:
1/2 in size and 164.8W/in
Keeping up with telecom trends
PAH450S48 is the power module developed for
telecom power amplifiers. Supporting the latest
industry developments, our telecom customers can
rest assured that we’ll keep up with the trends.
For third and later generation cell phones, high-speed
communication is critical. Base station transmission
amplifiers must achieve as high output power as
possible to cater for high-speed communication and
traffic increases. The next-generation transmission
amplifiers must meet many other conditions, such as
small size, low cost and high energy efficiency.
Our product doesn’t meet only the de facto industry
standards in terms of shape and input voltage etc.
which comprise the basic specifications, but also
has high output power. Also, it is compact and highly
efficient, and making it an ideal power supply for the
next generation of transmission amplifiers.
○Size: half-brick size(industry standard)
○Input Voltage: VDC48, common in the telecom industry
○Output Power: 450W
Previously, 350W was the maximum output
capacity with our half brick sized power modules
with 48Vin and 28Vout, but PAH450S48 takes
a dramatic leap forward to 450W. Also, we
used to have no other choice for 350W+ than
full-brick size before, but from now on the
half-brick is all you need.

48VDC input
Wide operating temperature range:
-40 to +100°C (baseplate)
Support for gallium nitride (GaN) devices
The long-awaited compound semiconductor,
GaN (gallium nitride) is now coming introduced.
This new semiconductor has captured the
attention of the telecommunications industry as
a semiconductor that enables to operate at
high voltages and high current densities, which
was impossible with previous semiconductors.
PAH450S48 supports the GaN device.
For a base station transmission amplifier, which is
installed outside, a wide operating temperature
range is essential. Users have the peace of mind
of being able to use this product within a wide
operating temperature range of -40 to +100°C.
