LINEAR TECHNOLOGY LT3579EFE-1#PBF 直流-直流开关升压, 反相稳压器, 可调, 2.5V-16V输入, 6A输出, 2.5MHz, TSSOP-20
The is a PWM DC-to-DC Converter with built-in fault protection features to aid in protecting against output shorts, input/output overvoltage and over-temperature conditions. The part consists of a 42V master switch and a 42V slave switch that can be tied together for a total current limit of 6A. The LT3579 is ideal for many local power supply designs. It can be easily configured in boost, SEPIC, inverting or flyback configurations and is capable of generating 12V at 1.7A or -12V at 1.2A from a 5V input. In addition, the LT3579"s slave switch allows the part to be configured in high voltage, high power charge-pump topologies that are very efficient and require fewer components than traditional circuits. The LT3579"s switching frequency range can be set between 200kHz and 2.5MHz. The part may be clocked internally at a frequency set by the resistor from the RT pin to ground or it may be synchronized to an external clock.
