200-W 48-V INPUT, 8-V OUTPUT, SEMI-REGULATED, ISOLATED DC-DC BUS CONVERTER
200-W Output
Input Voltage Range: 36 V to 75 V
The PTQB425080 power module is single-output
isolated DC/DC converter, housed in an industry
Meets 100 V, 100 ms Input Transient
standard
quarter-brick
package.
The
module
is
6:1 Input-to-Output DC Conversion Ratio:
nominally rated up to 200 W with a maximum load
36 V to 55 V Input
current of 25 A. It delivers an output voltage of 1/6th
10.5 V Output Voltage Limit: > 55 V Input
the input voltage for an input voltage range of 36 V to
55 V, while limiting the output voltage to 10.5 V for an
93% Efficiency
input voltage greater than 55 V.
1500 V
DC Isolation
The PTQB425080 operates from a standard 48-V
On/Off Control
telecom central office (CO) supply and occupies only
Overcurrent Protection
3.3 in2 of PCB area. The module offers OEMs a
Over-Temperature Shutdown
compact and flexible high-output power source in an
industry standard footprint. It is suitable for distributed
Undervoltage Lockout
power applications in both telecom and computing
SmartSync External Clock Drive (Optional)
environments
that
utilize

architecture (IBA), and may be used for powering
downstream point-of-load (POL) devices such as the
Standard 1/4-Brick Bus Converter Footprint
second generation PTH series of products (T2).
UL Safety Agency Approval
Features include a remote On/Off control with
optional logic polarity, and an undervoltage lockout
(UVLO).
Protection
features
include
output
over-current protection (OCP) and over-temperature
protection (OTP). To compliment T2-POL products,
optional features include a SmartSync compatible
clock drive and a AutoTrack power-up sequencing
manager
The
module
is
fully
integrated
for
stand-alone
operation, and require no additional components.
