Power-supply designers can choose from a plethora of available positive buck regulators that can also serve as negative boost DC/DC converters. Some buck regulators have a negative-feedback reference voltage expressly for this purpose, but ICs that ...
Most battery chargers comprise nothing more than a series-pass regulator with current limit. In solar-powered systems, you can’t count on sufficient headroom to keep a series regulator alive, so a shunt method is preferred. A simple shunt ...
Linear Technology announces the LT6109 , a complete high side current sense device that incorporates a current sense amplifier, dual comparators and a precision 400mV voltage reference. When connected to a current shunt resistor, the high side ...
Linear Technology announced a new high reliability MP-grade version of the LT1431 , a three-terminal adjustable shunt voltage regulator that operates over a -55 C to 150 C junction temperature range. This device has a 100mA sink capability, 0.4% ...
Bin Wu, Analog Devices Design Note 572 Introduction The LT8672 is an active rectifier controller that (along with a MOSFET) provides reverse current protection and rectification for power supplies in automotive environments. This job is ...
Numerous and evil are the forces of darkness that conspire to frustrate accurate analog-to-digital conversion of wide-dynamic-range analog signals. Among these gremlins lurk common-mode-voltage noise and signal amplitudes too variable to fully use ...
Figure 1 shows a chopped amplifier that requires only 5.5 µA supply current. Offset Voltage is 5 µV, with 0.05 µV/ C drift. A gain exceeding 10 8 affords high accuracy, even at large closed-loop gains. Figure 1. 0.05 µV/ C ...
Designed to drive high-current LEDs at constant current, the H-grade version LT3517 LED drivers features a 3 to 30-V input voltage range with a transient protection to 40 V. The part operates with a junction temperature up to 150 C and can drive up ...
The bandpass filter circuit shown in Figure 1 features an electronically controlled Q. Q for a bandpass filter is defined as the ratio of the 3 dB pass bandwidth to the stop bandwidth at some specified attenuation. The center frequency of the ...
Linear Technology Corporation announces the LT8300 , a low quiescent current monolithic flyback regulator that significantly simplifies the design of an isolated DC/DC converter. No optocoupler, third winding or signal transformer are required for ...
