MAX8969
Step-Up Converter
for Handheld Applications
General Description
The MAX8969 is a simple 1A step-up converter in a small
package that can be used in any single-cell Li-ion appli-
cation. This IC provides protection features such as input
undervoltage lockout, short circuit, and overtemperature
shutdown.
The IC transitions to skip mode seamlessly under light-
load conditions to improve efficiency. Under these
conditions, switching occurs only as needed, reducing
switching frequency and supply current to maintain high
efficiency.
When the input voltage is sufficient to drive the load, the
IC can be operated in track mode or automatic track
mode (ATM). In track mode, the p-channel MOSFET acts
as a current-limited load switch and quiescent current is
as low as 30μA under a no-load condition. In ATM mode,
the p-channel MOSFET acts as a current-limited load
switch and quiescent current is as low as 60μA under a
no-load condition. In ATM mode, the internal boost cir-
cuitry is enabled, allowing for fast transitions into boost
mode.
The IC is available in a small, 1.25mm x 1.25mm, 9-bump
WLP (0.4mm pitch) package.
