Product Introduction
The MAX662A is a regulated +12V, 30mA-output, chargepump DC-DC converter. It provides the necessary +12V ±5% output to program byte-wide flash memories, and requires no inductors to deliver a guaranteed 30mA output from inputs as low as 4.75V. It fits into less than 0.1in² of board space. The MAX662A is a pin-compatible upgrade to the MAX662, and is recommended for new designs. The MAX662A offers lower quiescent and shutdown currents, and guarantees the output current over all temperature ranges.
The MAX662A is the first charge-pump boost converter to provide a regulated +12V output. It requires only a few inexpensive capacitors, and the entire circuit is completely surface-mountable.
A logic-controlled shutdown pin that interfaces directly with microprocessors reduces the supply current to only 0.5μA. The MAX662A comes in 8-pin narrow SO and DIP packages.
The MAX662A provides a regulated 12V output voltage at 30mA from a 5V ±5% power supply, making it ideal for flash EEPROM programming applications. It uses internal charge pumps and external capacitors to generate +12V, eliminating inductors. Regulation is provided by a pulse-skipping scheme that monitors the output voltage level and turns on the charge pumps when the output voltage begins to droop.
