Micrel Eliminates Dual-Stage Conversion For Point-Of-Load Applications With High-Efficiency, Wide-Input Switching Regulator IC
Newest Member Of SuperSwitcher II(TM) Family Has Micrel’s Hyper Speed Control(TM) Delivering Ultra-Fast Transient Response And Minimizing Output Capacitance While Achieving Highest Power Density
Micrel Inc., (Nasdaq:MCRL), an industry leader in analog, high-bandwidth communications and Ethernet IC solutions, is now supporting volume quantities of the MIC28510, a wide-input synchronous switching regulator IC that provides step-down conversion with:
- better than 94 percent peak efficiency
- from an input voltage as high as 75V
- with maximum output current of 4A.
This solution eliminates the need for a costly dual-stage conversion approach for point-of-load applications. The MIC28510 delivers up to 100W of power in a 13cm2 device – a new standard for power density.
Benefiting from Micrel’s proprietary adaptive on-time control architecture, the MIC28510 provides ultra-fast transient response for today’s demanding applications such as base stations, Power-over-Ethernet, home security systems and solar inverters. The MIC28510 integrates features like:
- low-Rds(on),
- high-side and low-side power switches (to provide a highly efficient output down to 0.8V
- a programmable switching frequency of up to 500 kHz
- an enable pin for very low power shutdown
- internal soft start
- under-voltage lockout and internal compensation
The MIC28510 is also Any Capacitor stable independent of output ESR, thus solving the stability problem power supply designers face with distributed output capacitance.
The device also provides a host of protection features such as:
- pre-bias safe start-up
- over temperature protection
- fold-back current limit
- short circuit protection
- a -40-deg C to 125-deg C junction temperature range.
The MIC28510 is available in a lead free 28-Lead 5mm x 6mm MLF(R) package.

ISSI Announces Sampling of RLDRAM(R) 3 Memory
Helps Enable 100G Ethernet and Transport Applications
Integrated Silicon Solution, Inc. (Nasdaq:ISSI), a leader in advanced memory solutions, is sampling RLDRAM 3 memory. RLDRAM 3 memory offers a 576Mb density with the DRAM industry’s fastest random access times (tRC). The device is ideally suited to 100G networking applications such as Packet Optical Transport, Carrier Ethernet Switches and Routers (CESR), and Core and Edge Routers.
Service providers are combining residential, business, and mobile services onto a single IP network. This is driving the need for a cost-effective, high-performance memory with fast random access rates (tRC). RLDRAM 3 memory offers a new Multibank WRITE feature that allows random READ accesses every 2ns – on par with high-speed SRAM but with the density and cost-effectiveness that comes with DRAM.
ISSI offer RLDRAM 3 memory in Industrial and Commercial temperature ranges and in Leaded and Lead-free packages.
