12v、30ma闪存存储器编程电源概述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 requiresno inductors to deliver a guaranteed 30ma output from inputs as lowas 4.75v. it fits into less than 0.1in2 of board space. the max662ais a pin-compatible upgrade to the max662, and is recommended fornew designs. the max662a offers lower quiescent and shut-downcurrents, and guarantees the output current over all temperatureranges.
the max662a is the first charge-pump boost converter to provide aregulated +12v output. it requires only a few inexpensivecapacitors, and the entire circuit is completelysurface-mountable.
a logic-controlled shutdown pin that interfaces directly withmicroprocessors reduces the supply current to only 0.5μa. themax662a comes in 8-pin narrow so and dip packages.
for higher-current flash memory programming solutions, refer to thedata sheets for the max734 (120ma output current, guaranteed) andmax732 (200ma output current, guaranteed) pwm, switch-mode dc-dcconverters.
or, refer to the max761 data sheet for a 150ma, pfm switch-modedc-dc converter that operates from inputs as low as 2v.关键特性regulated +12v ±5% outputvoltage4.5v to 5.5v supply voltagerangefits in 0.1in2guaranteed 30ma outputno inductor—uses only 4capacitors185μa quiescent currentlogic-controlled 0.5μashutdown8-pin narrow so and dippackages应用/使用+12v闪存编程电源
