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 battery-powered 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. The MAX608 is available in 8-pin DIP and SO packages.

Product Detail

The MAX608 evaluation kit (EV kit) provides a regulated 5V or adjustable output voltage from an input source as low as 1.8V. It drives loads up to 0.5A with greater than 80% conversion efficiency.

This EV kit is a fully assembled and tested surface-mount circuit board. Additional pads on the bottom of the board accommodate the external feedback resistors for setting different output voltages.
