LCD panels are available from stock
Sharp Microelectronics LCD panels are available from stock in sizes ranging from 3.5in QVGA up to 15in TFT XGA.
The 4:1 input range of the convertors supply up to 100W of usable power and suits industrial, mobile, medical and telecom applications.
The UQQ convertor series employs an interleaved, synchronous-rectifier topology that exploits 100% of the duty cycle.
These devices simultaneously achieve ultra-high efficiency up to 91%, tight line/load regulation, low noise and quick step response.
The single-board, open-frame design offers a reduced component count, low on-resistance FETs and planar magnetics embedded in heavy-copper PC boards.
From a 9-36 or 18-75V input, the UQQ series delivers outputs of 3.3, 5, 12, 15 or 24V and measures 37 x 58 x 11mm.
The industry standard footprint carries on/off control (positive or negative polarity), output trim (+10/-20%) and output sense functions.
An optional base plate keeps the package below 12.7mm, providing more usable power in applications with little or no air flow.
The UQQ's feature set includes high isolation, input pi filters, input undervoltage shutdown, output overvoltage protection, current limiting, short-circuit protection and thermal shutdown.
These convertors have a standard quarter-brick package (pinout in through-hole version), are fully isolated up to 2250V DC and have UL/EN/EIC60950 safety approvals.
