Linentrifra introduces the H-level version of the boost DC / DC controller LTC3872

Linear Technology Corporation launches the H-level version of the LTC3872, which is a 550KHz fixed frequency boost type DC / DC controller with a small board area. It is specified in -40 ° C to 150 ° C. Work within the temperature range. LTC3872 accepts 2.5V to 9.8V input voltage range, which can generate up to 60V output voltages without detecting resistors. If you use a detection resistor, the output voltage is limited only by external components. LTC3872 can drive large N-channel MOSFETs that produce large peak output currents. When powered with a 5V bias voltage, the switching voltage can rise to up to 60V, which is very suitable for automotive, heavy equipment and industrial control applications. The current mode architecture of the LTC3872 provides cyclical limit flow and superior transient responses. The pulse jump mode of light load reduces the static current to 250ua, which helps extend the running time of the battery-powered application in the standby mode. Other features include internal soft start, adjustable current limits, precise undervoltage locked, and strict ± 1.6% reference voltage accuracy over the entire operating temperature range of -40 ° C to 150 ° C. LTC3872H uses heat-resistant reinforced 2mm x 3mm DFN-8 packages and 8 lead Thinsottm package. A thousand batch prices are $ 2.35 per piece.
