Diodes Inc. : new compact power packages, LED drivers, switching regulators&omni-polar hall sensors Search Home About Products News Quality Extras Registration HomeContact us Diodes Inc. :new compact power packages, LED drivers, switching regulators & omni-polar hall sensors The acquisition of Anachip Corporation, a Taiwanese fab-less analog IC company, has enabled Diodes Inc to expand it’s product portfolio. Search Go search for part number search entire site Manufacturers Select one of our dedicated manufacturer sections H&L fused IEC Inlet Mains Filters have European approvals A new compact Power package: With a 75% PCB footprint area saving over the SMA and a low profile 0.7 mm max height, the PowerDI TM323 is rated at a remarkable 500mW to 750mW depending on PCB layout. The PowerDI TM323 product offering includes a comprehensive line of Schottky rectifiers optimized for low power consumption to conserve battery power. Schottkys include the PD3S0230, a drop-in compatible alternative to the BAT254 packaged in SOD110. Additional Schottkys include the PD3Sxx series offering low forward voltage and reverse leakage versions rated up to 1A forward current. The PowerDI TM323 product offering also includes a 500mW rated PD3Zxx Zener series which is a drop-in compatible alternative to the BZX284C series (SOD110) and the PD3SD2580 switching diode is offered as a drop-in replacement to the BAS216 (SOD110). Click Here Rate this page 1:Poor 5:Excellent 1 2 3 4 Traditionally centered around subminiature surface-mount discrete devices, the acquisition brings adjacent technologies including Hall-effect ICs, analog power management ICs like linear and switching regulators, Operational Amplifiers, Comparators, Reset ICs and USB Power Switches. 5 The PowerDI TM323 package completes the PowerDI TM123 and PowerDI TM5 families. The PowerDI TM123 features a 1W package power dissipation and is a drop-in equivalent to packages known in the industry as SOD-123FL, SMF or SMP and M1F. It is also a potential replacement for products offered in the SOD87 package. The low profile, package (1.0mm max height) offers a 59% PCB area reduction from SMA. The PowerDI TM5 family provides a 1.5W power dissipation, a max package height of 1.15mm, and a 48% PCB area reduction versus SMC. All PowerDI parts are qualified to the AEC-Q101 standards for high reliability and are compliant with RoHS environmental standards. AP15xx switching regulator family The AP1501 is a monolithic 150Khz PWM Buck DC/DC Converter capable of driving a 3A load without requiring external transistors. With a high input voltage rating up to 45V, AP1501 has embedded internal over-current protection (OCP) with current limiting and oscillation frequency switching down to protect the chip. The AP1501 is a competitive alternative to the LM2596. The AP1510, a 3A step-down switching regulator with PWM control, provides low-ripple power, high efficiency and excellent transient characteristics. On chip protection includes externally adjustable OCP and internal current limiting. The typical efficiency is 91%, higher than the AP1501. The wide input voltage range from 3.6V to 23V is well suited for use in adapter-based high input voltage applications including ADSL Modems, Telecom Equipment, LCD Monitors, DVD-Video Player and PC Motherboards. http://www.anglia.com/newsarchive/1559.asp (1 of 2) [18/05/2007 10:51:10] Diodes Inc. : new compact power packages, LED drivers, switching regulators&omni-polar hall sensors The AP1537 is a 2A step-down switching regulator with PWM control. With an input voltage range up to 18V, it is perfect for use in LCD monitors, telecom equipment, computer peripherals, etc. AP1537 features ultra high efficiency with MLCC type external capacitors, saving cost and improving performance. AP1537 also includes built-in OCP function with current limiting provides short circuit protection. AH180- Low Power omni-polar Hall Effect Switch The AH180, sensing the presence of either a north or south magnetic field, is optimized to meet the low-power, low operating voltage requirements of electronic sensing applications such as position sensor in battery powered portable equipment. It is particularly suitable for cover detector applications in cellular phones and notebook PCs. By sensing both magnetic polarities, the omni-polar hall sensor eliminates the need to orient the magnet polarity, increasing end product manufacturing ease. The AH180 has an oscillator integrated that maintains a 0.1% duty cycle for on-time and a latched open drain output. The output of the Hall-effect sensor during sample time is latched and held until the next sample occurs. This technique allows for an average supply current less than 15 µA, making the device a perfect fit for battery powered applications. AH180 operates from the -40°C to +85°C temperature range and is available in three packages which include 3-pin SIP, SC-59 and the space saving low profile DFN package. The Omni-polar Hall Family will be completed early 2007 with a 24V input voltage version with a typical operating current of 1.5mA targeting industrial applications.
