DC/DC开关稳压器, 可调节, 降压, 双, 2.7V至5.5V输入, 3.6V/1.5AOut, 2.2Mhz, TQFN-16
The from Products is a dual 2.2MHz, low voltage step down DC to DC converter in 16 pin TQFN package. This high efficiency, dual synchronous converter operates with a 2.7V to 5.5V input voltage and provides a 0.8V to 3.6V output voltage range. The device delivers up to 1.5A of load current per output. The low input/output voltage range and ability to provide high output currents make this device ideal for on-board point of load and post regulation applications. It features a 2.2MHz fixed frequency PWM mode for better noise immunity and load transient response and skip mode for increased efficiency during light load operation. The 2.2MHz frequency operation allows for an all-ceramic capacitor design and small size external components. An optional spread spectrum frequency modulation minimizes radiated electromagnetic emissions due to the switching frequency. Typical application includes automotive post regulation, industrial/military.
