Abstract: We don't expect manufacturers to produce clothes that in one size that fits everyone. In thesame way, one ESD component can't solve all issues—each application has different ESD requirements.Knowing that "one size fits all" cannot apply to power design, the power designer, or the engineering"super hero," must consider all the potential disruptions to a steady flow of power and thenvarious waysto mitigate them. This tutorial describes voltage- and current-limiting devices and risetime reducers tomanage the power. It also points to free and low-cost software tools to help design lowpass filters, checkcapacitor self-resonance, and simulate circuits.

Abstract: This document details the Riverside (MAXREFDES8#) subsystem reference design, a 3.3V input, 12V (15V) output, isolated power supply. The Riverside reference design includes a 3W primary-side transformer H-bridge driver for isolated supplies, and one wide input range and adjustable output low-dropout linear regulator (LDO). Test results and hardware files are included.

Abstract: Uses the MAX641 switching controller and an external discrete charge pump to step up the input voltage. This circuitcan service low loads and is efficient when the output is two, three, four times the input voltage. Adding the MAX627 MOSdriver can further increase the output current capability.

The core voltages for FPGAs are moving lower as a resultof advances in the fabrication process. The newest FPGAfamily from Altera, the Stratix® II, now requires a corevoltage of 1.2V and the Stratix, Stratix GX, HardCopy®Stratix and CycloneTM families require a core voltage of1.5V. This article discusses how to power the core and I/Oof low voltage FPGAs using the latest step-down switchmode controllers from Linear Technology Corporation.

高的工作電壓高達(dá)100V N雙N溝道MOSFET同步驅(qū)動 The D810DCDC is a synchronous step-down switching regulator controller that can directly step-down voltages from up to 100V, making it ideal for telecom and automotive applications. The D810DCDC uses a constant on-time valley current control architecture to deliver very low duty cycles with accurate cycle-by-cycle current limit, without requiring a sense resistor. A precise internal reference provides 0.5% DC accuracy. A high bandwidth (25MHz) error amplifi er provides very fast line and load transient response. Large 1Ω gate drivers allow the D810DCDC to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. Integrated bias control generates gate drive power from the input supply during start-up and when an output shortcircuit occurs, with the addition of a small external SOT23 MOSFET. When in regulation, power is derived from the output for higher effi ciency.

Although recent popular attention is focused on LithiumIon batteries, one must not forget that other batterychemistries, such as Nickel Cadmium (NiCd) and NickelMetal Hydride (NiMH) have advantages in rechargeablepower systems. Nickel-based batteries are robust, capableof high discharge rates, have good cycle life, do notrequire special protection circuitry and are less expensivethan Li-Ion. Among the two, NiMH batteries are rapidlyreplacing NiCd because of their higher capacity (40% to50% more) and the environmental concerns of the toxiccadmium contained in NiCd batteries.
