Linear launches high temperature H-level version of heat resistance enhanced LTC3122

Milpitas, CAs, CA, CA, Milpitas, CAs - Linear Technology Corporation launched a high temperature H-level version of LTC3122, which uses 12 lead heat-resistant performance enhanced MSOP packages. LTC3122 is a 3MHz, current mode, synchronous boost type DC / DC converter that is integrated with output disconnecting. Its inside 2.5A opens 1.8V (runtime 0.5V) to 5.5V input voltage range to provide up to 15V output voltage, so that the device is ideal for a variety of different battery chemical composition or standard 3.3V. And 5V power supply. The LTC3122 provides up to 800 mA continuous output current from 5V input at 12V output. Pin Optional burst mode (BURST MODE®) is operated to reduce the quiescent current to only 25μA, so that longer battery runs can be provided in hand-held applications. Its heat-resistant reinforced MSOP-12 packages are combined with a constant switching frequency of up to 3MHz to make designers to balance between printed circuit board solution size and desired efficiency. The H-level version is specified within the range of working knots in -40 ° C to + 150 ° C. Its electrical specifications are the same as the existing E and I versions. The H-level version is very suitable for automotive, industrial and military applications that have been suffered from high ambient temperatures. LTC3122HMSE adopts 12 lead heat resistance enhanced MSOP packages, thousands of batch prices are $ 2.98 per piece and there is a stock supply.
