1. Feature List

The EFP01 highlighted features are listed below.

• VOA

• Output Voltage: 1.7 V to 5.2 V

• DCDC A can be configured in Buck/Boost, Buck-only, or

Boost-only

• DCDC A output be combined with the VOC linear regulator

for more efficient regulation as the input voltage approaches

the output voltage

• Firmware-programmable switched output (VOA_SW) allows

complete powerdown of high leakage external circuitry in

low power modes

• VOB

• Output Voltage:

• 0.8 V to 3.3 V (EFP0101/03/06/09/11)

• 0.8 V to 1.26 V (EFP0102/04/07/08/10)

• DCDC B can be used only in Buck configuration

• Dedicated internal linear regulator in parallel provides more

efficient regulation as the input voltage approaches the out-

put voltage

• VOC

• Output Voltage: 1.7 V to 3.3 V

• Linear regulator only

• Can be used either to create an independent third output

supply or in conjunction with DCDC A

• Coulomb Counter

• Lossless (i.e. no sense resistor) measurement of charge in-

to the load

• Communication & Control

• Fully configurable I2C

• Direct Mode supports fast transitions between energy

modes

• IRQ pin to notify host processor

• Ultra-low EM2 Quiescent Current

• 150 nA with no outputs enabled

• 300 nA with a single output enabled

• +125 nA for each additional output enabled

• Safety

• Programmable inrush current

• Short-circuit tolerant outputs

• Under-voltage lock-out (UVLO) circuitry holds device in low-

est power reset state when VDDB is below 1.2 V

• Over-temperature monitoring and IRQ assertion

• Wide Operating Range

• 0.8 V to 5.5 V input power supply

• -40 to 100 °C junction temperature

• QFN20 3x3 mm Package
