The MAX1640/MAX1641 CMOS, adjustable-output, switch-mode current sources operate from a +5.5V to +26V input, and are ideal for microprocessor-controlled battery chargers. Charging current, maximum output voltage, and pulse-trickle charge are programmed with external resistors. Programming the off-time modifies the switching frequency, suppressing undesirable.
o 95% Efficiency o +5.5V to +26V Input Supply Range o 2V to 24V Adjustable-Output Voltage Range o 100% Maximum Duty Cycle (Low Dropout) o Up to 500kHz PWM Operation o Optional Synchronous Rectifier o 16-Pin QSOP Package o Current-Sense Accuracy: 2% (MAX1641) 5.3% (MAX1640) _______________General Description The MAX1640/MAX1641 CMOS, adjustable-output, switch-mode current sources operate from a +5.5V to +26V input, and are ideal for microprocessor-controlled battery chargers.
