Lineart launches the H-level version of LT3641

Linear Technology Corporation launches the H-level version of the LT3641, and the LT3641 is a dual channel, a current mode buck type switching regulator, a power-on reset and a watchdog timer. Its 4V to 42V input voltage range and ability to withstand 55V transients make this device very suitable for common loads and cold cars in automotive applications, which require constant outputs even when entering transients up to 55V adjust. LT3641 uses a unique dual channel design, a high input voltage (4VIN to 42VIN, 55VIN transient ability) The non-synchronous channel provides 1.3a output current; and another lower input voltage (2.5Vin to 5.5Vin) The synchronous channel provides a continuous output current of up to 1.1A. Although the device allows each channel to provide input separately, most applications powers with the output of the high voltage channel to the lower voltage channel, thereby providing a dual output while optimizing efficiency and switching frequency. For example, using a nominal 12V input and 2MHz switching frequency, the LT3641 provides 3.3V output at 600 mA through its high voltage channel, and provides 1.8 through its lower voltage channel at 800 mA at 90% sub-end efficiency. V Output. The H-level version can be taken up to 150? C. In contrast, the highest junction temperature of the E-level and I versions is 125? C. All electrical specifications of E, I and H-class versions are the same. The H-level device is tested and guarantees the highest junction temperature to 150? C, which is ideal for automobiles and industrial applications that are often at a high ambient temperature. LT3641HFE provides 28 lead heat-resistant TSSOP-28 packages, thousands of batch prices are $ 4.43 per piece and there is stock.
