12A Buck Converter

RT6242 is a high current buck converter featuring ultra low (12mΩ/5.4mΩ) Rdson MOSFETs. It is capable of delivering up to 12A load current. Its 4.5V-18V input range makes it suitable to be run from 5V or 12V supplies, and the output can be adjusted between 0.7V-8V. Richtek's propriety ACOT control topology delivers ultrafast transient capability, and is stable with low ESR MLCC output capacitors. It comes in PSM and Force-PWM versions and features programmable current limit, adjustable switching frequency, adjustable softstart and PGood in a compact UQFN-16JL 3x3 package. Highly suitable for powering FPGA, SoC and other low voltage high current rails.

More Info
Flexible LED driver

RT8462 is a multi-topology LED driver controller which can be used in buck, boost and buck-boost configurations with output (LED string) voltages up to 60V. The IC max input voltage is 36V, but the power stage can be fed from higher voltages. Accurate average LED current sense, Analog / PWM / PWM to analog dimming options, adjustable switching frequency, adjustable softstart and overcurrent / overvoltage protections make this a flexible choice for a wide range of LED driver applications.
