ISL6527, ISL6527A
Data Sheet
Single Synchronous Buck Pulse-Width
Modulation (PWM) Controller
The ISL6527, ISL6527A make simple work out of
implementing a complete control and protection scheme for
a DC/DC step-down converter. Designed to drive N-Channel
MOSFETs in a synchronous buck topology, the ISL6527,
ISL6527A integrate the control, output adjustment,
monitoring and protection functions into a single package.

Features
? Operates from 3.3V to 5V Input
? Utilizes an External Reference
? Drives N-Channel MOSFETs
? Simple Single-Loop Control Design
- Voltage-Mode PWM Control
? Fast Transient Response
FN9056.10
The ISL6527, ISL6527A provide simple, single feedback loop,
voltage-mode control with fast transient response. The output
voltage can be regulated to as low as the provided external
reference. 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.
