Linear Technology Corporation (Linear Technology Corporation) introduced a high reliability LTC3805 / -5 a (MP grade) version, the device is a programmable frequency flyback controller, junction to -55 ° C and 150 ° C Work in the warm range. This high performance parallel stable input voltage PWM (Pulse Width Modulation) controller operates from a wide input voltage range of 5V to off-line applications, making it ideal for users who need a single power supply to provide both 48V and 24V nominal input systems.

The LTC3805 /-5 features a current mode control architecture that provides excellent transient response and cycle-by-cycle current limit while simplifying feedback loop stability. The fixed operating frequency range is 70kHz to 700kHz and can be synchronized to an external clock. Small startup current (40uA) and operating current (360uA) minimize power loss and increase efficiency. Its low current limit of 100mV further reduces power loss. Other features include adjustable soft start, programmable slope compensation, remote on/off and overvoltage protection. The LTC3805 MP-5 has a lower turn-on voltage of 4.5V, while the LTC3805MP has a turn-on voltage of 8.4V.

The LTC3805MP/-5 version is available from stock in a thermally enhanced MSOP-10 package. The 1,000-piece purchase price is $4.76 per piece. For more information, please visit
