P1-P3P4-P6P7-P9P10-P12P13-P15
48Vdc/24Vdc Input, 3.3Vdc@25A Output
Quarter-brick Converter AVQ100-36S3V3
Document NO.: 31020993 August 31, 2011 Rev 2.0
·Description
The AVQ100-36S3V3 is a single output DC-DC
converter with standard quarter-brick outline
and pin configuration. It delivers up to 25A
output current with 3.3V output voltage. above
90% efficiency and excellent thermal
performance makes it an ideal choice to supply
power in telecom and datacom. It can work
under -40°C ~ +85°C. 18V ~ 60V wide input
range makes it possible for both 24V and 48V
power system application.
Operational Features
z Delivers up to 25A output current
z High efficiency: 90% (typ., full load, 48V).
92% (typ., half load, 24V)
z Wide input range: 18V ~ 60V
z Excellent thermal performance
z No minimum load requirement
z Start-up and shut-down monotonically into
any normal and pre-biased loads, internal
pre-bias function circuit prevents back
negative current drawn from external load
z RoHS 5/6,RoHS 6/6 compliant
Control Features
z Remote control function (negative or
positive logic optional)
z Remote output sense
z Trim function: 80% ~ 110%
Protection Features
z Input under voltage lockout
z Output over current protection
z Output over voltage protection
z Over temperature protection
Mechanical Features
z Industry standard quarter-brick pin-out
outline
z open frame structure and with baseplate
option
z Pin length option: 3.8mm, 4.8mm, 5.8mm
Safety & EMC
z Meets safety standards UL 60950-1,
CSA-C22.2 NO.60950-1, IEC/EN 60950-1
and GB4943.
z Approved by UL and TUV.
z Meets 2006/95/EEC and 93/68/EEC
directives which facilitates CE marking in
user’s end product
z Meets conducted emission's requirements
of FCC Class (and EN55022 Class A with
external filter.
