I. Device Description
A. General
The MAX1523 is a simple, compact boost controller designed for a wide range of DC-DC conversion topologies, including
step-up, SEPIC, and flyback applications. It is for applications where extremely low cost and small size are top priorities.
This device is designed specifically to provide a simple application circuit and minimize the size and number of external
components, making them ideal for PDAs, digital cameras, and other low-cost consumer electronics applications.
This device uses a unique fixed on-time, minimum off-time architecture, which provides excellent efficiency over a wide-range
of input/output voltage combinations and load currents. The fixed on-time is pin selectable to either 0.5µs (50% max duty
cycle) or 3µs (85% max duty cycle), permitting optimization of external component size and ease of design for a wide range
of output voltages.
The MAX1523 operates from a +2.5V to +5.5V input voltage range and is capable of generating a wide range of outputs. The
device has an internal soft-start and short-circuit protection to prevent excessive switching current during startup and under
output fault conditions. The MAX1523 reenters soft-start mode during output fault conditions. The MAX1523 is available in a
space-saving 6-pin SOT23 package.
