Product Overview

The LTC3588EMSE-1#PBF is a nanopower energy harvesting Power Supply operates at 2.7 to 20V input operating range. It integrates a low-loss full-wave bridge rectifier with a high efficiency buck converter to form a complete energy harvesting solution optimized for high output impedance energy sources such as piezoelectric, solar or magnetic transducers. An ultralow quiescent current under-voltage lockout (UVLO) mode with a wide hysteresis window allows charge to accumulate on an input capacitor until the buck converter can efficiently transfer a portion of the stored charge to the output. In regulation, the LTC3588-1 enters a sleep state in which both input and output quiescent currents are minimal. The buck converter turns on and off as needed to maintain regulation. However, the output capacitor may be sized to service a higher output current burst. An input protective shunt set at 20V enables greater energy storage for a given amount of input capacitance.
  • 950nA Input quiescent current (output in regulation - no load)
  • 450nA Input quiescent current in UVLO
  • Integrated low-loss full-wave bridge rectifier
  • Up to 100mA of output current
  • Selectable output voltages of 1.8, 2.5, 3.3, 3.6V
  • High efficiency integrated hysteretic buck DC/DC
  • Input protective shunt up to 25mA pull-down at VIN >=20V
  • Wide input under-voltage lockout (UVLO) range
