UNITY POWER FACTOR LED LAMP DRIVER

General Description The HV9931 is a fixed frequency PWM controller IC designed to control an LED lamp driver using a single-stage PFC buckboost-buck topology. It can achieve a unity power factor and a very high step-down ratio that enables driving a single high-brightness LED from the 85-264VAC

2MHz to 1.6GHz 45dB RF-Detecting Controllers and RF Detector

General Description The MAX9930–MAX9933 low-cost, low-power logarithmic amplifiers are designed to control RF power amplifiers (PA) and transimpedance amplifiers (TIA), and to detect RF power levels. These devices are designed to operate in the 2MHz to 1.6GHz frequency range. Features ♦
