+12V, 30mA Flash Memory Programming Supply MAX662A
_____General DescriptionThe 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, andrequires no inductors to deliver a guaranteed 30mA out-put from inputs as low as It fits into less than board space. The MAX662A is a pin-compatibleupgrade to the MAX662, and is recommended for newdesigns. The MAX662A offers lower quiescent and shut-down currents, and guarantees the output current over alltemperature MAX662A is the first charge-pump boost converter toprovide a regulated +12V output. It requires only a fewinexpensive capacitors, and the entire circuit is complete-ly logic-controlled shutdown pin that interfaces directlywith microprocessors reduces the Supply current to A. The MAX662A comes in 8-pin narrow SO and DIPpackages. For higher-current Flash Memory Programming solutions,refer to the data sheets for the MAX734 (120mA outputcurrent, guaranteed) and MAX732 (200mA output cur-rent, guaranteed) PWM, switch-mode DC-DC , refer to the MAX761 data sheet for a 150mA, PFMswitch-mode DC-DC converter that operates from inputsas low as +12V Flash Memory Programming SuppliesCompact +12V Op-Amp SuppliesSwitching MOSFETs in Low-Voltage SystemsDual-Output +12V and +20V Supplies_____Features
MAX662A _____Detailed Description Operating Principle The MAX662A provides a regulated 12V output voltage at 30mA from a 5V ±5% power supply, making it ideal for …
