MAX662A 12V, 30mA Flash Memory Programming Supply

The MAX662A is a regulated +12V, 30mA-output, charge- pump DC-DC Converter It provides the necessary +12V 5% output to program byte-wide Flash Memories an requires no inductors to deliver a guaranteed 30mA out- 2 put from inputs as low as 4.75V. It fits into less than 0.1in 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 shut- down 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 complete- ly surface-mountable. A logic-controlled shutdown pin that Interfaces directly with Microprocessors reduces the supply current to only 0.5A. The MAX662A comes in 8-pin narrow SO and DI packages. For higher-current Flash memory programming solutions, refer to the data sheets for the MAX734 (120mA output current, guaranteed) and MAX732 (200mA output cur- rent, 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.
