3-Output SIMO Buck-Boost Converter
HL7783
Message
HL7783 is a single-inductor, multiple-output (SIMO) buck-boost, DC-to-DC converter designed for applications that require ultra-low supply current and small solution size.
A single inductor is sued to regulate three separate outputs, saving board space while delivering higher total system efficiency than equivalent power solutions using multiple bucks and/or linear regulators.
An input voltage range is 2.7V to 5.5V. Its output voltage range is either 0.6V to 5.175V in 25mV steps, programmable through an I2C interface for I2C version or 0.6V to 4.6V of resistor-value based output for non I2C version. Its output voltage can be adjusted on the fly on both HL7783WL01 (OTP option) and HL7783WL02 (I2C version).
.
The HL7783 is available in 16-Bump, 0.4mm pitch WLCSP package with 1.89mm x 1.89mm size.
