TDK Corporation announces the introduction of TDK-Lambda’s CPFE1000FI of baseplate/conduction-cooled 1000W power supplies. When compared to TDK-Lambda’s MIL-STD rated CPFE1000F, the overall product size has been reduced by 60%. Capable of operating without forced-air cooling, the supplies are suited to outdoor, sealed enclosure, communications and harsh environment industrial applications, including RF amplifier and ground-based satellite […]
Power Supplies
Light detection and amplification
A common sensor requirement is to measure light. This may be for adjusting the brightness of a display or for instrumentation where accuracy is of importance and light levels could be very low. The light could be relatively constant or slowly changing, or it could be modulated at high speed. There are a number of […]
Fast half-bridge gate driver handles 600-V MOSFETs, IGBTs
Texas Instruments (TI) introduced the industry’s fastest half-bridge gate driver for discrete power MOSFETs and IGBTs that operate up to 600 V. The UCC27714 high-side, low-side driver with 4-A source and 4-A sink current capability reduces component footprint by 50 percent, enabling higher power density in high-frequency, offline AC/DC power supplies used in server, telecom […]
Programmable power supply sequencer, voltage supervisor handles six voltage rails
Linear Technology Corporation introduces the LTC2937, a programmable power supply sequencer and voltage supervisor, with built-in EEPROM, for six voltage rails. The LTC2937 is designed to carefully supervise and control FPGA/ASIC/microprocessor point-of-load supplies, which require tight accuracy and complex sequencing to avoid damage to the processor. The LTC2937 turns supplies on and off in a […]
Supply converts 40~72 Vdc input to 12 Vdc output
CUI Inc announced an addition to its line of 1100 W front-end power supplies to include dc input versions. The PSD-1100-12 series delivers high power density and achieves Platinum efficiency in a compact slim line 1U package measuring just 1.575 x 2.145 x 12.65 inches (40 x 54.5 x 321.3 mm). The narrow 54 mm […]

TVS diodes absorb 24 A during lightning strikes
Littelfuse, Inc., a manufacturer in circuit protection, has introduced two new product series, the SP4044 and SP4045 Series TVS Diode Arrays (SPA® Diodes), designed to protect sensitive electronics from destructive electrostatic discharges (ESD) and lightning-induced surge events. Low capacitance diodes are integrated with an additional zener diode to protect each I/O pin against ESD and high […]
Diodes Incorporated enables cost-effective headset detection with low power IC in miniature package
The AZV5001 headset detection IC introduced by Diodes Incorporated is targeted at cost- and power-sensitive consumer electronics such as mobile phones, tablet computers and media players. The integration of a comparator, OR gate and N‑channel MOSFET into a miniature package enables the connection of a headset with microphone to be quickly and simply detected. The […]
Ultra low power switching regulators
For micropower applications there are some interesting new devices around for helping power the circuitry. I am not thinking here about energy harvesting applications but low power battery operated devices where you don’t want the battery to go flat quickly when in standby but still need some regulated power to wake up a microcontroller, for […]
