MAXIM INTEGRATED / ANALOG DEVICES MAX643ACPA Step-Up Regulator
The MAX643ACPA+ is a fixed-output, 10W CMOS step-up switching regulator housed in an 8-pin DIP package. Designed primarily for minimal component DC-DC converter circuits, it is preset to provide a +15V output voltage but can be adjusted to other levels by adding two resistors. The device operates over a voltage range of 2V to 16.5V and features a 50kHz oscillator frequency at +15V with a 50% duty cycle. It consumes approximately 0.75mA of supply current at the output voltage of +15V and has an internal reference voltage of 1.31V at 25°C. The regulator offers an efficiency of around 80% with an external MOSFET, line regulation of 0.08%, and load regulation of 0.2%. It includes an on-chip driver suitable for driving high-power external MOSFETs and is ideal for power management applications in industrial, portable devices, uninterruptible power supplies, and battery systems.
