Description
General part information
MAX662A Series
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, 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 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 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.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.Applications+12V Flash Memory Programming SuppliesCompact +12V Op-Amp SuppliesDual-Output +12V and +20V SuppliesSwitching MOSFETs in Low-Voltage Systems
