Circuit breaker handles Voltages to 32V:  05/25/00 EDN-Design Ideas / (added 2/06) The simplicity of low-side current monitoring can mask the advantages of a high-side approach. You can monitor load currents in a power supply, a motor driver, or another power circuit on either the high or the low side (ground). However, don't let the ease of low-side monitoring cause you to overlook its dangers or the advantages of a high-side approach. Various fault conditions can bypass the low-side monitor, thereby subjecting the load to dangerous and undetected stresses. On the other hand, a high-side monitor connected directly to the power source can detect any downstream failure and trigger the appropriate corrective action. Traditionally, such monitors required a precision op amp, a boost power supply to accommodate the op amp's limited common-mode range, and a handful of precision resistors. Now, the MAX4172 IC can sense high-side currents in the presence of common-mode...

Configure buck converter for boost operation :  12/17/98 EDN-Design Ideas  / (added 2/06)    Buck converters are inherently different from boost converters, because buck converters typically use the high side of the output as the power switch’s reference. However, a buck converter with a floating output drive section is configurable as a boost controller (Figure 1). This circuit configures the SC1101 buck controller for a 5 to ±12V boost with ±500 mA of output current. The BST pin, which normally connects to a high-side drive supply in a buck converter, connects to VCC to drive the ground-referenced MOSFET. By tying PGND to circuit ground, the SC1101 becomes a boost controller, yielding 12V from 5V. An output charge-pump voltage inverter provides –12V at 0.5A as well....

Controller IC and One Shot Form Resonant Controller:  11/28/02 EDN Design Ideas  /  (added 1/05)  Resonant power supplies are popular because of high efficiency, low noise, and compactness. You can implement a resonant buck or boost converter using a single switch. The regulation of the output in such a converter derives from using a constant on or off time and a variable frequency. The UC1864 controller IC (Texas Instruments, www....

EPLD configures wait-state generator :  02/03/97 EDN Design Ideas / (added 2/06)   Using a faster microcontroller or microprocessor in an existing application can boost the performance of a system. Unfortunately, interfacing the faster processor to the much slower existing peripheral ICs is a complex task. To overcome this problem, new processors, such as Philips XA, have an external wait-state-insertion capability. Given this wait-state feature, the tricky part is to generate the wait-state signal itself. In many cases, you can use one-shot ICs, such as the 74HCT221. Unfortunately, these ICs have a slow response time. This Design Idea shows how to build a wait-state generator with a fast response time (5 nsec, typically) using an EPLD. A benefit of using an EPLD is that you can integrate other glue logic, such as address decoding, into the EPLD....
