Power Factor Correction Controllers
ISL6730A, ISL6730B, ISL6730C, ISL6730D
The ISL6730A, ISL6730B, ISL6730C, ISL6730D are active
power factor correction (PFC) controller ICs that use a boost
topology. (ISL6730B, ISL6730C, ISL6730D are Coming Soon.)
The controllers are suitable for AC/DC power systems, up to
2kW and over the universal line input.
The ISL6730A, ISL6730B, ISL6730C, ISL6730D are operated
in continuous current mode. Accurate input current shaping is
achieved with a current error amplifier. A patent pending
breakthrough negative capacitance technology minimizes zero
crossing distortion and reduces the magnetic components
size. The small external components result in a low cost design
without sacrificing performance.
The internally clamped 12.5V gate driver delivers 1.5A peak
current to the external power MOSFET. The ISL6730A,
ISL6730B, ISL6730C, ISL6730D provide a highly reliable
system that is fully protected. Protection features include
cycle-by-cycle overcurrent, over power limit, over-temperature,
input brownout, output overvoltage and undervoltage
protection.
The ISL6730A, ISL6730B provide excellent power efficiency
and transitions into a power saving skip mode during light load
conditions, thus improving efficiency automatically. The
ISL6730A, ISL6730B, ISL6730C, ISL6730D can be shut down
by pulling the FB pin below 0.5V or grounding the BO pin. The
ISL6730C, ISL6730D have no skip mode.
Features
• Reduce component size requirements
- Enables smaller, thinner AC/DC adapters
- Choke and cap size can be reduced by 66%
- Lower cost of materials
• Excellent power factor over line and load regulation
- Internal current compensation
- CCM Mode with Patent pending IP for smaller EMI filter
• Better light load efficiency
- Automatic pulse skipping
- Programmable or automatic shutdown
• High reliable design
- Cycle-by-cycle current limit
- Input average power limit
- OVP and OTP protection
- Input brownout protection
• Small 10 Ld MSOP package
Applications
• Desktop computer AC/DC adaptor
• Laptop computer AC/DC adaptorhttp://www.DataSheet4U.net/
Two switching frequency options are provided. The ISL6730B,
ISL6730D switch at 62kHz, and the ISL6730A, ISL6730C
switch at 124kHz.
• TV AC/DC power supply
• AC/DC brick converters
