RECENTLY INTRODUCED IN INDIA, FROM NEAR AND FAR
supply controllers. These devices detect no-load conditions and signal the power supply to enter a low-consumption ‘ off’ mode. Integrated features include constant-voltage and constant-current regulation as well as optional built-in LED driver for adaptor indicator light.

Stmicroelectronics has introduced a voltage- level translator compliant with Secure Digital ( SD) 13.0 standard. The ST6G3244 couples high-speed operation with very low power dissipation, supported with the power-down mode. Data integrity is secured through propagation delays, electromagneticinterference filters and signal conditioning.
The translator incorporates 15kv air-gap electrostatic discharge protection on the card side. The selectablesupply (1.8V or 2.9V), 6-bit bidirectional Cmos-level translator for SD, mini-sd and micro-sd memory card is offered in BGA25 package.

Low-loss SIC power devices
Renesas Electronics Corporation has launched three silicon-carbide (SIC) power devices with voltage tolerance of 600V.
The RJQ6020DPM device for critical- conduction- mode power factor correction (PFC) applications combines in a single package an Sic-schottky barrier diode (SBD) and two high- voltage power MOSFETS. The reverse recovery time of SIC-SBD is 15 nanoseconds. The RJQ6021DPM device for continuous-conduction-mode PFC applications combines in a single package an SIC-SBD and two insulated-gate bipolar transistors. The RJQ6022DPM device for inverter half-bridge circuits combines in a single package two SICSBDS and two IGBTS.
