FEATURES
DESCRIPTION
Input Range: 1.6-V to 6-V
Integrated Power Diode and Isolation FET
The TPS61093 is a 1.2-MHz, fixed-frequency boost
converter designed for high integration and high
20-V Internal Switch FET With 1.1-A Current
reliability. The IC integrates a 20-V power switch,
Fixed 1.2-MHz Switching Frequency
input/output isolation switch, and power diode. When
Efficiency at 15-V Output up to 88%
the output current exceeds the over load limit, the
IC’s isolation switch opens up to disconnect the
Over Load and Over Voltage Protection
output from the input. This protects the IC and the
Programmable Soft Start-up
input supply. The isolation switch also disconnects
Load Discharge Path After IC Shutdown
the output from the input during shutdown to minimize
leakage current. When the IC is shutdown, the output
2.5 × 2.5 × 0.8 mm SON Package
capacitor is discharged to a low voltage level by
internal diodes. Other protection features include

1.1-A peak over-current protection (OCP) at each

cycle, output over voltage protection (OVP), thermal

shutdown, and under voltage lockout (UVLO).
3.3-V to 12-V, 5-V to 12-V Boost Converter
With its 1.6-V minimum input voltage, the IC can be
powered by two alkaline batteries, a single Li-ion
battery, or 3.3-V and 5-V regulated supply. The
output can be boosted up to 17-V. The TPS61093 is
available in 2.5 mm × 2.5 mm SON package with
thermal pad.
