ISL6526, ISL6526A

Single Synchronous Buck Pulse-Width Modulation (PWM) Controller

The ISL6526, ISL6526A make simple work out of

implementing a complete control and protection scheme for

a DC/DC stepdown converter. Designed to drive N-Channel

MOSFETs in a synchronous buck topology, the ISL6526,

ISL6526A integrate the control, output adjustment,

monitoring and protection functions into a single package.

The ISL6526, ISL6526A provide simple, single feedback

loop, voltage-mode control with fast transient response. The

output voltage can be precisely regulated to as low as 0.8V,

with a maximum tolerance of ±1.5% over-temperature and

line voltage variations. A fixed frequency oscillator reduces

design complexity, while balancing typical application cost

and efficiency.

The error amplifier features a 15MHz gain-bandwidth

product and 6V/µs slew rate which enables high converter

bandwidth for fast transient performance. The resulting

PWM duty cycles range from 0% to 100%.

Protection from overcurrent conditions is provided by

monitoring the r

DS(ON)

of the upper MOSFET to inhibit PWM

operation appropriately. This approach simplifies the

implementation and improves efficiency by eliminating the

need for a current sense resistor.
