Linear Techology’s LT8705 is a buck-boost switching controller that operates from input voltages above, below, or equal to the output voltage. It has four feedback loops to regulate the input ...

Buck regulators are usually the first choice when you design nonisolated step-down regulators unless the ratio of V IN to V OUT is greater than 10, the input voltage is high, or both. Low duty cycle ...

Renesas has brought out a family of bidirectional four-switch synchronous buck-boost controllers. The ISL81601 and ISL81401 are true bidirectional controllers that sense peak current at both ends and ...

A synchronous rectifier is an electronic switch that improves power-conversion efficiency by placing a low-resistance conduction path across the diode rectifier in a switch-mode regulator. MOSFETs ...

One of the latest Linear Technology dc-to-dc converter ICs is the LTC3124, whose application circuit is shown in Fig. 1. Fig. 1. The LTC3124features fixed frequency, current mode PWM control for good ...

Linear Technology announces the LT8391, a synchronous buck-boost DC/DC LED controller that regulates LED current from input voltages above, below and equal to the output voltage. Its 4V to 60V input ...

The LTC3777 is a 150V high efficiency (up to 99%) 4-switch synchronous buck-boost DC/DC controller, which operates from input voltages above, below or equal to the regulated output voltage. Its 4.5V ...

The LT3791 is a synchronous 4-switch buck-boost LED driver controller that can regulate LED current up to 52V of LED string with input voltages above, below, or equal to the output voltage. The ...

Eyeheight has introduced the AV-2M, an SD-HD SDI emergency switcher that will perform clean switchover to a secondary source if the primary channel falls below user-adjustable parameters. Designed for ...
