Tool Description:

The MAX761 CMOS DC-DC converter is a versatile step-up supply. It operates from inputs as low as 1.8V, consumes only 200ȘA of supply current, and fits in 0.3inȘ. Its output voltage is pre-set to 12V+/-5%, or can be adjusted from 3V to 16V with just two resistors. Efficiency ranges from 80% to 88% for most applications.
The high efficiency of these devices is the result of low quiescent current and a unique, current-limited, pulse-frequency-modulated (PFM) control scheme. The device combines the benefits of pulse-width-modulated (PWM) converters (high efficiency at heavy loads), with the benefits of PFM converters (low quiescent supply currents).
These 8-pin devices save space, since they have an internal 1A power MOSFET and require as few as four small external components. Their high switching frequency (up to 300KHz) allows the use of small surface-mount components.
Other features include a logic-controlled shutdown mode (1ȘA supply current) and a built-in LBI/LBO low-battery detector.
The MAX761 is available in 8-pin SOIC and DIP packages in the commercial (0ȘC to +70ȘC), extended industrial (-40ȘC to +85ȘC), and military (-55ȘC to +125ȘC) temperature ranges. A pre-assembled surface-mount evaluation kit (MAX761EVKIT-SO) is available to speed designs.
