MAX662ACSA

The MAX662ACSA is a regulated +12V, 30mA-output, charge-pump 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 MAX662ACSA is a pin-compatible upgrade to the MAX662, and is recommended for new designs. The MAX662ACSA offers lower quiescent and shut-down currents, and guarantees the output current over all temperature ranges. The MAX662ACSA 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 MAX662ACSA comes in 8-pin narrow SO and DIP packages. For higher-current flash memory programming solutions, refer to the data sheets for the MAX734 (120mA output current, guaranteed) and MAX732 (200mA output current, guaranteed) PWM, switch-mode DC-DC converters.Or, refer to the MAX761 data sheet for a 150mA, PFM switch-mode DC-DC converter that operates from inputs as low as 2V.
