30V/50mA LED 驱动

The ETA1638 is a driver specially designed for back-lighting. It consists of a high accuracy current sink that allows low duty dimming and a high efficiency step-up converter with an integrated low side and high side power MOSEFT. It runs with an optimal 0.6MHz frequency that enables use of small ex • Synchronous Boost, No Schottky Diode Needed\n\n• Internal Current Source Driving, no need of external current setting resistor\n\n• ±10% LED Current Accuracy at 1% Diming Ratio\n\n• Capable of 0.1% dimming ratio\n\n• Up to 85% Efficiency (6 LEDs)\n\n• Drive up to 8 LEDs\n\n• 30V Ou;

Low voltage IF I/Q transceiver

DESCRIPTION The SA1638 is a combined Rx and Tx IF I/Q circuit. The receive path contains an IF amplifier, a pair of quadrature down-mixers, and a pair of baseband filters and amplifiers. A second pair of mixers in the transmit path transposes a quadrature baseband input up to the IF frequency. An
