Ceramic Input
Capacitors Can Cause Overvoltage Transients: AN88 - Linear Technology - When it comes to input filtering, ceramic capacitors are a
great choice. They offer high ripple current rating and low ESR and ESL. Also, ceramic capacitors are not very sensitive to over voltage and
can be used without derating the operating voltage. However, designers must be aware of a potential overvoltage condition that is generated
when input voltage is applied abruptly. After applying an input voltage step, typical input filter circuits with ceramic capacitors can
generate voltage transients twice as high as the input voltage. Application Note 88 describes how to efficiently use ceramic capacitors for
input filters and how to avoid potential problems due to input voltage transients. |

Supercapacitor Boosts current from small Battery:
09/02/04 EDN Design Ideas / (added 1/05) Some battery-powered devices require large amounts of current in a short period of
time but spend most of the time in sleep (power-down) mode. The momentary large-load current demands large batteries to meet the time
requirement, even though the average current consumption is low. For instance, a system operates for 1.... |
