ETA1093
1MHz, Forced-PWM, High Output current Synchronous Step-Up Converter
DESCRIPTION
FEATURES
ETA1093 is an ETA Solutions’ high efficiency, high frequency
synchronous Step-Up converter, capable of delivering output
current up to 3A at a 5V output from a 3.6V input. With a low
Rdson Power MOS and a built-in synchronous rectifier, its
efficiency can be as high as 93% at a 5V/2.1A load. This greatly
minimizes power dissipation and reduces heat on the IC,
making it ideal for applications that require small board space
and have stringent temperature constraints, such as power
banks and mobile devices. ETA1093 also incorporates ETA
Up to 97% Energy Converting Efficiency
Up to 3A output current at 5V output, 3.6V input
Externally adjustable output voltage
True Shut off during shutdown and output short-
circuit protection
Thermal Shutdown
Forced PWM at light load

overload and short-circuit conditions. All of these features are
integrated in a tiny QFN3x3-16 package. With 1MHz switching
frequency, small external input and output capacitors and
inductor can be used.

ETA1093 employs a FORCED-PWM control scheme, therefore,
the switching frequency is fixed at any load. It makes ETA1093
perfect for systems that sensitive to low frequency noise, like
audio system and communication system.
