Analog Devices Circuit Note CN0191 Circuit Function and Benefits The circuit shown in Figure 1 provides a programmable 20-bit voltage with an output range −10 V to +10 V, 1 LSB integral nonlinearity, 1 LSB differential nonlinearity, and low ...

Jian Li, Yingyi Yan and Marvin Macairan, Linear Technology Design Note 542 Introduction The LTM4675 is a dual 9 A or single 18 A step-down uModuleR (micromodule) DC/DC regulator featuring remote configurability and telemetry monitoring of power ...

By combining charge-pump ICs with additional discrete components, this inverting design produces a negative output from a positive one with lower ripple and output impedance. An inverting charge pump takes a positive supply voltage and generates a ...

Choosing between two widely available, multisourced ICs for the core of an inductorless dc-dc converter the NE555 timer and the LM386 audio amplifier requires a look at their key specifications and performance in typical circuits. The bipolar NE555 ...

Richard Cook, Linear Technology LT Journal of Analog Innovation Multicell high capacity batteries are increasingly becoming commonplace in handheld devices and industrial instruments that receive their power from a variety of sources. To maximize ...

Valentin Kulikov, Futuro Lighting EDN Introduction This article describes simple constant current driver module with fast PWM input that can be used for driving medium and high power LEDs. The module uses an integrated constant-current output, ...

The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q 2 , which energizes the load. The load current is limited by negative ...

Jian Li and Gina Le, Linear Technology Design Note 524 Digital Power System Management: Set, Monitor, Change, and Log Power Managing power and implementing flexibility in a high rail count circuit board can be challenging, requiring hands-on ...

Marty Merchant, Linear Technology Design Note 507 Introduction Dual-polarity supplies are commonly needed to operate electronics such as op amps, drivers, or sensors, but there is rarely a dual-polarity supply available at the point of load. The ...

David Burgoon, Linear Technology LT Journal of Analog Innovation There are several ways to produce a negative voltage from a positive voltage source, including using a transformer or two inductors and/or multiple switches. However, none are as easy ...
