PWM Controller Utilizes Emulated-Current-Mode
Updated: 2014-11-28 10:10:38 (GOBRIGHT NEWS DEPT)
National Semiconductor has introduced a pulse-width modulation (PWM) buck controller that employs National's emulated-current-mode (ECM) architecture for output voltages with low duty cycles at frequencies up to 1.5 MHz. The LM3495 powers digital application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), digital signal processors (DSPs) and other embedded processors. Deep sub-micron ICs require tight regulation accuracies in order to perform, and the LM3495 offers accuracy of plus or minus 1 percent over a wide temperature range. It has a host of system integration features optimized for these applications. The LM3495 also addresses the additional requirements of? point-of-load (POL) module manufacturers with fault-protection features that ensure a reliable end product.
National's LM3495 expands the power management portfolio, giving designers a choice between The LM274x family. Both architectures allow designers to reach very high operating frequencies and conversion ratios without having to deal with switching noise headaches. The LM3495 has a 200 kHz to 1.5 MHz switching frequency that can be synchronized to reduce radiated system noise. Its on-chip gate drivers are capable of driving FETs suitable for output currents in excess of 20A. The LM3495 has soft shutdown and glitch-free start-up into pre-biased loads to ensure deep sub-micron cores are not damaged. The LM3495, available in a TSSOP-16 package, operates from a single input rail, eliminating the need for an external bias supply.Available now, the LM3495 is priced starting at US$3.08 in 1,000-unit quantities.
