ISL6545, ISL6545A

5V or 12V Single Synchronous Buck Pulse-Width Modulation (PWM) Controller

FN6305

Rev 7.00

October 7, 2015

The ISL6545, ISL6545A makes simple work out of

implementing a complete control and protection scheme for a

Features

• Operates from +5V or +12V Supply Voltage (for bias)

DC/DC stepdown converter driving N-Channel MOSFETs in a

synchronous buck topology. Since it can work with either 5V or

12V supplies, this one IC can be used in a wide variety of

applications within a system. The ISL6545, ISL6545A

(hereafter referred to as “ISL6545x”, except as needed)

integrates the control, gate drivers, output adjustment,

monitoring and protection functions into a single 8 Ld SOIC or

10 Ld DFN package.

- 1.0V to 12V V Input Range (up to 20V possible with

restrictions; see Input Voltage Considerations)

- 0.6V to V Output Range

- Integrated Gate Drivers use V

(5V to 12V)

- 0.6V Internal Reference; ±1.0% tolerance

• Simple Single-Loop Control Design

- Voltage-Mode PWM Control

The ISL6545x provides single feedback loop, voltage-mode

control with fast transient response. The output voltage can be

precisely regulated to as low as 0.6V, with a maximum

tolerance of ±1.0% over-temperature and line voltage

variations. A selectable fixed frequency oscillator (ISL6545 for

300kHz; ISL6545A for 600kHz) reduces design complexity,

while balancing typical application cost and efficiency.

- Drives N-Channel MOSFETs

- Traditional Dual Edge Modulator

• Fast Transient Response

- High-Bandwidth Error Amplifier

- Full 0% to 100% Duty Cycle

• Lossless, Programmable Overcurrent Protection

- Uses Lower MOSFET’s r

DS(ON)

The error amplifier features a 20MHz gain-bandwidth

product and 9V/µs slew rate which enables high converter

bandwidth for fast transient performance. The resulting

PWM duty cycles range from 0% to 100%.

• Small Converter Size in 8 Ld SOIC or 10 Ld DFN

- 300kHz or 600kHz Fixed Frequency Oscillator

- Fixed Internal Soft-Start, Capable into a Pre-biased

Load

Protection from overcurrent conditions is provided by

- Integrated Boot Diode

monitoring the r

of the lower MOSFET to inhibit PWM

DS(ON)

- Enable/Shutdown Function on COMP/SD Pin

- Output Current Sourcing and Sinking

operation appropriately. This approach simplifies the

implementation and improves efficiency by eliminating the

need for a current sense resistor.

• Pb-Free (RoHS Compliant)
