This document describes the 4100 series surface mount toroidal inductors from C&D Technologies (NCL) Limited. These inductors are designed for use in switching power supplies and DC/DC converters, and feature compact, low-profile designs.
PT500 Series is a 500W family of multiple-output power supplies with a 3.3V main output. It supports wide-range input and is compliant with FCC and VDE Class B EMI standard. It also features active PFC, remote sense compensation, output voltage adjustment, remote inhibit, power fail warning, and thermal shutdown.
The NMD series of DC-DC converters are ideally suited to applications where a potential difference exists between loads, eg motor control circuits. The twin outputs offer cost and space savings by consolidating two DC-DC Converters into one package. All of the rated power may be drawn from a single output provided the total load does not exceed 1 Watt.
The NMV series of industrial temperature range DC-DC converters are the standard building blocks for on-board distributed power systems. They are ideally suited for providing local supplies on control system boards with the added benefit of 3kVDC galvanic isolation to reduce switching noise. Available in SIP and DIP with dual and single output pinout. All of the rated power may be drawn from a single pin on dual output variants provided the total load does not exceed 1watt.
The 78253 series of converter transformers are specifically designed for use with the MAX253 chip set to provide isolated power supplies. The 5V version can supply 1W and the 3.3V version can supply 500mW. A centre tapped secondary winding allows for full bridge, half bridge or voltage doubling. The surface mount devices are fully compatible with CECC00802 to 280°C which allows them to be placed and reflowed with IC’s thus reducing time and cost in production.
The VKA60xS Series DC/DC converters present an economical and practical solution for distributed power system architectures which require high power density and efficiency while maintaining system modularity and upgradeability. With the ability to operate over a wide input voltage range of 18 to 36 and 33 to 75 volts, these modules are ideal for use in battery backup applications common in today's telecommunication and electronic data processing applications. The output is fully isolated from the input, allowing for a variety of polarity and grounding configurations. The VKA60xS's proprietary control circuitry responds to 50-100% load steps in 100µSeconds to within 1% nominal Vout. The patented fixed frequency architecture combined with surface mount technology results in a compact, efficient and reliable solution to DC/DC conversion requirements. Safety per UL1950, EN 60950 and CSA 22.2 #234.
The NPH15S series of DC-DC Converters combines ease of application with versatility. It features high efficiency, high power density, input-output isolation, industry standard pinout, UL 1950 recognition, and more.
The NMA 5V & 12V series is an isolated 1W dual output DC-DC converter with wide temperature performance, dual output, industry standard pinout, power sharing on output, 1kVDC isolation, efficiency up to 78%, high power density, etc.
This document describes the features and characteristics of the HB04U series products, including high isolation, low leakage current, internal filtering, etc.
The LME series of DC-DC converters are optimised for low-power operation. Due to the low quiescent current they are able to offer efficiencies up to 75%. The use of advanced magnetics ensures a minimal quiescent current of around 2.5mA which ensures that efficiency is maximised in low power applications. They are ideally suited to generating a negative supply where only a positive rail exists.
