Add Trimmable Current Limit to DC-to-DC Supply: 08/01/97 EDN Design Ideas / (added 6/06) You can add a simple, two-transistor
circuit to a standard, step-down dc/dc converter to provide an adjustable limit for output current. You can apply this method to most step-down converters that provide access to feedback
node. |

Add-On Current Limiter by Ron J: This circuit allows you to set a limit on maximum output current available from your PSU. It's
very useful when you power-up a project for first time or carry out a soak-test. By setting an upper limit on current available from your PSU you can protect both your power supply and any
device connected to it. (added 10/05) |

|
Circuit Provides Hiccup Current Limiting: 06/26/03 EDN Design Ideas / (added 1/05) Current-limit protection is an essential
feature for power-supply systems. The three major types of current-limit-protection mechanisms are constant, foldback, and hiccup. Hiccup current limit performs the best of the three types;
however, the implementation is rather complex. In this scheme, upon detection of an overcurrent event, the whole power supply shuts down for an interval before it tri...... |

Comparator Adds Current Limit to V2 Controller: 05/21/98 EDN-Design Ideas / (added 6/06) The subroutine "FASTBCD" (Listing 1)
for 8051 µPs quickly converts 16-bit binary to 24-bit BCD data. The conversion algorithm involves left-shifting bits from the high-order bit of the binary number into the carry bit while
left-shifting the carry bits into the low-order bit of a BCD shift register using BCD left-shift operations. .... |

Current Limiting Power Supply: This is a 1-amp variable-voltage PSU. It adjusts from about 3v to 24v: and has the added feature
that you can limit the maximum output current. This is invaluable when (for example) you power-up a project for the first time or soak-test a piece of equipment. added 10/05) |

Rechargeable Flashlight Obsoletes Lantern Battery: 12/11/03 EDN Design Ideas / (added 1/05) This Design Idea describes a
high-intensity, rechargeable flashlight system that you can build from a 6V lantern-type flashlight. The rechargeable battery comprises four 2V, 2.5-Ahr (ampere-hour) SLA (sealed lead-acid)
cells, similar in size to a standard D-sized battery. SLA cells are especially well-suited to powering flashlights because of their low self-discharge rate.... |
