Applications
* Total output error is less than ±1% over load, line, and temperature. The MAX8855/MAX8855A operate in PWM mode with a switching frequency ranging from 0.5MHz to 2MHz, set by an external resistor. It can also be synchronized to an external clock in the same frequency range. Two internal switching re
