Low Input Voltage and High Efficiency Synchronous Boost Converter with 1.3A

Switch

The ISL9113 provides a power supply solution for devices

Features

• Up to 95% efficiency at typical operating conditions

Li-Ion/Li-Polymer batteries. It offers either a fixed 5V or an

adjustable output option for USB-OTG or portable HDMI

applications. The device is guaranteed to supply 500mA from

a 3V input and 5V output and has a typical 1.3A peak current

limit. High 1.8MHz switching frequency allows for the use of

tiny, low-profile inductors and ceramic capacitors to minimize

the size of the overall solution.

• Input voltage range: 0.8V to 4.7V

• Output current: Up to 500mA (V_BAT= 3.0V, V_OUT= 5.0V)

• Low quiescent current: 20μA (typical)

• Logic control shutdown (I_Q< 1µA)

• Fixed 5V, 5.1V or adjustable output

• 1.2V EN high logic

The ISL9113 is an internally compensated, fully integrated

synchronous converter optimized for efficiency with minimal

external components. At light load, the device enters skip

mode and consumes only 20µA of quiescent current, resulting

in higher efficiency at light loads and maximum battery life.

• Output disconnect during shutdown

• Skip mode under light load condition

• Undervoltage lockout

The device is available in an 8 Ld DFN package and a 6 bump

WLCSP.

• Fault protection: OVP (ADJ version only), OTP, short circuit

• 8 Ld 2mmx2mm DFN package and 6 bump

0.8mmx1.36mm WLCSP
