MAX608 data sheet and three typical application circuit diagrams

description:

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 An operating frequency of up to 300 kHz 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.
