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 ...
To discover potential power-supply problems, you must run dynamic and static tests. This simple current sink tests low- to medium-power supplies and voltage sources. In this application, the current sink can draw current of 0 to 1.5 A for an ...
John Rice, Texas Instruments LEDs Magazine The non-synchronous, boost, power-conversion topology is often used in LED drivers in instances where the input voltage (VIN) is insufficient to forward bias a series/parallel set of LED strings. This ...
This Design Idea is a solid state relay (SSR) which uses a triac to switch AC loads at high current. There are plenty of simple SSR circuits available, but this may be the simplest circuit that achieves turn-on and turn-off only when the AC line ...
Sensors, electrostatic traps, and other applications require regulated, high-voltage power supplies that deliver modest amounts of output current. Simplicity, low quiescent current, and compactness are desirable in such supplies. The circuit of ...
Assume that a design requires positive voltage, but only a negative-voltage power source is available. Using a standard boost-converter IC in the circuit of Figure 1, you can efficiently generate a positive voltage from a negative source. The boost ...
Mike Rose EDN Using the fast dynamic load described in this Design Idea to test the transient response of a power system can reveal many critical operating characteristics. The voltage deviation resulting from a fast current step can provide ...
Tom Gross, Linear Technology Design Note 511 Introduction The LTC3626 synchronous buck regulator with current and temperature monitoring is the first of Linear’s SWITCHER+™ line of monolithic regulators. It is a high efficiency, ...
