Lineart launches the H-class and MP version of LTC3851A

Linear Technology Corporation launches LTC3851A's H-class and MP-level versions, which have a wide input voltage range (4V to 38V), which is suitable for a variety of applications. Most intermediate bus voltages and battery chemical composition. The powerful built-in MOSFET gate driver allows the use of high-power external MOSFETs to generate up to 25A output current in the output voltage range of 0.8V to 5.5 V, which is ideally satisfied with the requirements of the load point. These H-level and MP-level version devices have been tested, and their work temperature range is ensured at -40 ° C to 150 ° C and -55 ° C to 150 ° C. Applications include automotive systems, industrial, medical, data communications and telecommunications. Constant frequencies, current mode architecture allows the optional fixed frequency or phase-locked loop (PLL) frequency at 250 kHz to 750 kHz. The output current detection can be completed by measuring the pressure drop across the output inductor (DCR) or using an optional detection resistor. In the case of short circuit and overload, the current fold returns the amount of heat generated by the MOSFET. Optional continuous, pulsed jumps or burst modes work is user control to optimize light load efficiency. The LTC3851A / -1 has a 99% duty cycle, with a very low differential pressure voltage, which is a very useful feature for extending the running time of battery power applications. Other features include tracking and adjustable soft start. The LTC3851A-1 and the LTC3851A differ in that the LTC3851A-1 has a good signal, not adjustable current limits. Both LTC3851AH / -1 and LTC3851AMP / -1 use heat-resistant enhanced MSOP-16 packages. The thousands of batch prices of H-class and MP-level devices were $ 2.24 and $ 5.29, respectively.
