Asynchronous vs. synchronous topologies. How a synchronous boost LED controller minimizes efficiency losses. The challenge of low-input-voltage operation. High-power LEDs continue to proliferate in ...
Buck-boost converters are popular solutions to cope with a wide-input voltage range that fluctuates below or above the desired output voltage. The conventional two-switch buck-boost converter offers ...
Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, ...
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's new synchronous buck boost converter, the LTC2129, is designed to deliver up to 200mA of continuous output current and a quiescent current of only 1.3µA. The device has an input ...
