ISM 433 MHz ASK Transmitter

General Description The AS3902 is a single channel low power 433 MHz ASK transmitter. It uses a fully integrated PLL stabilized RF-oscillator which avoids frequency pulling by approaching the antenna with objects as it occurs at SAW resonator based transmitters. ASK modulation is performed by swi

18V 2A 500kHz Synchronous Step-Down DC/DC Converter

 GENERAL DESCRIPTION The AX3902 is a high efficiency, 2A current mode synchronous step down DC/DC converter with a wide input voltage range from 4.5V to 18V. The device integrates high side and low si de MOSFETs to achieve high efficiency conversion. The current mode architecture supports fast
