DESCRIPTION
The LTC® 3520 combines 1A buck-boost and 600mA synchronous buck DC/DC converters in a tiny 4mm × 4mm package. A programmable switching frequency allows the efficiency to be optimized while minimizing the solution footprint. Both converters feature soft-start and current limit protection. The uncommitted gain block can be configured as an LDO or utilized as a battery- good
comparator.FEATURES
Dual High Effi ciency DC/DC Converters:
Buck-Boost (VOUT: 2.2V to 5.25V, IOUT= 1A at VOUT= 3.3V, VIN≥ 3V)
Buck (VOUT: 0.8V to VIN , IOUT= 600mA)
2.2V to 5.5V Input Voltage Range
Pin-Selectable Burst Mode® Operation
Uncommitted Gain Block for LDO Controller, Battery Good Indication or Sequencing
Programmable 100kHz to 2MHz Switching Frequency
55μA Total Quiescent Current for Both Converters in Burst Mode Operation
Thermal and Overcurrent Protection
<1μA Quiescent Current in Shutdown
