REGULATOR

DCDC穩壓器印刷電路板設計

The LTM8020, LTM8021, LTM8022 and LTM8023 μModule®REGULATORs are complete easy-to-use encapsulated stepdownDC/DC REGULATORs intended to take the pain and aggravationout of implementing a switching power supplyonto a system board. With a μModule REGULATOR, you onlyneed an input cap, output cap and one or two resistorsto complete the design. As one might imagine, this highlevel of integration greatly simplifi es the task of printedcircuit board design, reducing the effort to four categories:component footprint generation, component placement,routing the nets, and thermal vias.

P54C-VR奔騰(R)微處理器的電源模塊

Providing power for the Pentium® microprocessor family isnot a trivial task by any means. In an effort to simplify thistask we have developed a new switching REGULATOR controlcircuit and a new linear REGULATOR to address the needs ofthese processors. Considerable time has been spent developingan optimized decoupling network. Here are severalcircuits using the new LTC®1266 synchronous buck REGULATORcontrol chip and the LT®1584 linear REGULATOR toprovide power for Pentium processors and Pentium VREprocessors. The Pentium processor has a supply requirementof 3.3V ±5%. The Pentium VRE processor requires3.500V ±100mV.

XL6003 300KHz 36V Boost 3W LED

The XL6003 REGULATOR is fixed frequency PWM Boost (step-up) DC/DC converter, capable ofdriving 1050mA load current with excellent line and load regulation. The REGULATOR is simple to use because it includes internal frequency compensation and a fixed-frequency oscillator so that it requires a minimum number of external components to work. The XL6003 could directly drive 5~10 3W LED units at VIN=12V.

DN492-雙單片降壓集成溫度監控模塊

Multioutput monolithic REGULATORs are easy to use and fi tinto spaces where multichip solutions cannot. Nevertheless,the popularity of multioutput REGULATORs is temperedby a lack of options for input voltages above 30V andsupport of high output currents. The LT3692A fi lls thisgap with a dual monolithic REGULATOR that operates frominputs up to 36V. It also includes a number of channeloptimization features that allow the LT3692A’s per-channelperformance to rival that of multichip solutions.

如何測試穩壓器的負載瞬態響應

Semiconductor memory, card readers, microprocessors,disc drives, piezoelectric devices and digitally based systemsfurnish transient loads that a voltage REGULATOR mustservice. Ideally, REGULATOR output is invariant during a loadtransient. In practice, some variation is encountered andbecomes problematic if allowable operating voltage tolerancesare exceeded. This mandates testing the REGULATORand its associated support components to verify desiredperformance under transient loading conditions. Variousmethods are employable to generate transient loads, allowingobservation of REGULATOR response

The Kalman filter is an efficient recursive filter that estimates the state of a linear dynamic syst

The Kalman filter is an efficient recursive filter that estimates the state of a linear dynamic system from a series of noisy measurements. It is used in a wide range of engineering applications from radar to computer vision, and is an important topic in control theory and control systems engineering. Together with the linear-quadratic REGULATOR (LQR), the Kalman filter solves the linear-quadratic-Gaussian control problem (LQG). The Kalman filter, the linear-quadratic REGULATOR and the linear-quadratic-Gaussian controller are solutions to what probably are the most fundamental problems in control theory.
