描述：

The MAX608 low-voltage step-up controller operates from a 1.8V to 16.5V input voltage range. Pulse-frequency- modulation （PFM） control provides high efficiency at heavy loads， while using only 85μA （typical）

when operating with no load. In addition， a logic-controlled shutdown mode reduces supply current to 2μA typical. The output voltage is factory-set at 5V or can be adjusted from 3V to 16.5V with an external resistor divider. The MAX608 is ideal for two- and three-cell batterypowered systems. An operating frequency of up to 300kHz allows use with small surface-mount components. The MAX608 operates in “bootstrapped” mode only（with the chip supply， OUT， connected to the DC-DC output）。 For a 12V output without external resistors， or for nonbootstrapped applications （chip supply connected to input voltage）， refer to the pin-compatible MAX1771.
