ISL6551

ZVS Full Bridge PWM Controller

FN9066

Rev 7.00

Oct 28, 2015

The ISL6551 is a zero voltage switching (ZVS) full-bridge PWM

controller designed for isolated power systems. This part

implements a unique control algorithm for fixed-frequency ZVS

current mode control, yielding high efficiency with low EMI. The

two lower drivers are PWM controlled on the trailing edge and

employ resonant delay while the two upper drivers are driven

at a fixed 50% duty cycle.

Features

• High speed PWM (up to 1MHz) for ZVS full bridge control

• Current mode control compatible

• High current high-side and low-side totem-pole drivers

• Adjustable resonant delay for ZVS

• 10MHz error amplifier bandwidth

• Programmable soft-start

This IC integrates many features in 28 Ld SOIC package to

yield a complete and sophisticated power supply solution.

Control features include programmable soft-start for

controlled start-up, programmable resonant delay for zero

voltage switching, programmable leading edge blanking to

prevent false triggering of the PWM comparator due to the

leading edge spike of the current ramp, adjustable ramp for

slope compensation, drive signals for implementing

• Precision bandgap reference

• Latching shutdown input

• Non-latching enable input

• Adjustable leading edge blanking

• Adjustable dead time control

synchronous rectification in high output current, ultra high

efficiency applications and current share support for

• Adjustable ramp for slope compensation

• Fast short-circuit protection (hiccup mode)

• Adjustable cycle-by-cycle peak current limiting

• Drive signals to implement synchronous rectification

• VDD undervoltage lockout

paralleling up to 10 units, which helps achieve higher reliability

and availability as well as better thermal management.

Protective features include adjustable cycle-by-cycle peak

current limiting for overcurrent protection, fast short-circuit

protection (in hiccup mode), a latching shutdown input to turn

off the IC completely on output overvoltage conditions or other

extreme and undesirable faults, a non-latching enable input to

accept an enable command when monitoring the input voltage

• Current share support

• ±5% “in regulation” indication

and thermal condition of a converter and V undervoltage

• Pb-free (RoHS compliant)

lockout with hysteresis. Additionally, the ISL6551 includes

high current high-side and low-side totem-pole drivers to avoid

additional external drivers for moderate gate capacitance (up

to 1.6nF at 1MHz) applications, an uncommitted high

bandwidth (10MHz) error amplifier for feedback loop

compensation, a precision bandgap reference with ±1.5%

(ISL6551AB) or ±1% (ISL6551IB) tolerance across

recommended operating conditions and a ±5% “in regulation”

monitor.

Applications

• Full-bridge and push-pull converters

• Power supplies for off-line and Telecom/Datacom

• Power supplies for high end microprocessors and servers

Related Literature

• AN1002, 200W, 470kHz, Telecom Power Supply Using

ISL6551 Full-Bridge Controller and ISL6550 Supervisor and

Monitor.

In addition to the ISL6551, other external elements such as

transformers, pulse transformers, capacitors, inductors and

Schottky or synchronous rectifiers are required for a complete

power supply solution. A detailed 200W telecom power supply

reference design using the ISL6551 with companion Intersil

ICs, Supervisor and Monitor ISL6550, and Half-bridge Driver

HIP2100, is presented in application note AN1002.

In addition, the ISL6551 can also be designed in push-pull

converters using all of the features except the two upper

drivers and adjustable resonant delay features.
