| The circuit uses the familiar LM2575 step-down regulator from National Semiconductor. This circuit converts a positive-voltage step-down reg...
| A window comparator that monitors whether its input voltage Uin lies within a defined voltage window can be built using only a few component...
| The switching threshold of the MAX6509 temperature switch from Maxim can be programmed over a range of –40 °C to +125 °C using an external r...
| Overcurrent sensors using external low-resistance sense resistors are fairly common. However, the members of a new family of ICs from Maxim...
| Audio amplifier circuits with a single supply voltage have output coupling capacitors that produce audible clicking or popping sounds when t...
| The author encountered a problem with a microcontroller system in which the +5-V supply voltage did not decay to 0 V sufficiently quickly af...
| Conventional step-up switching regulator ICs need at least one external Schottky diode and have the disadvantage that there is no effective...
| The LTC4054 from Linear Technology is a very simple device for charging 4.2 V Li-ion batteries. This SMD IC comes in a five-pin SOT-23 packa...
| The circuit shown here can be used to convert a digital input signal having any desired duty cycle into a output signal having a duty cycle...
