MAX769 General Description
The MAX769 is a complete buck/boost power supply and monitoring system for two-way pagers or other lowpower digital communications devices. Few external components are required. Included on-chip are:
· An 80mA output, synchronous-rectified, buck/boost
DC-DC converter with a digitally controlled +1.8V to
+4.9V output. The DC-DC converter is unique, since
it provides a regulated output for battery inputs that
are both less than and greater than the output voltage,
without using transformers.
· Three low-noise linear-regulator outputs
· Three DAC-controlled comparators for softwaredriven,
3-channel A/D conversion
· SPI™-compatible serial interface
· Reset and low-battery (LBO) warning outputs
· Charger for NiCd/NiMH, lithium battery, or storage
capacitor for RF PA power or system backup
· Two 1.8½ (typical), serial-controlled, open-drain
MOSFET switches for beeper or vibrator drive An evaluation kit for the MAX769 (MAX769EVKIT) is available to aid in design and prototyping.
