FN4324.2
Buck and Synchronous-Rectifier
Features
Pulse-Width Modulator (PWM) Controller
• Drives Two N-Channel MOSFETs
• Operates From +5V or +12V Input
The HIP6012 provides complete control and protection for a
DC-DC converter optimized for high-performance
microprocessor applications. It is designed to drive two
N-Channel MOSFETs in a synchronous-rectified buck
topology. The HIP6012 integrates all of the control, output
adjustment, monitoring and protection functions into a single
package.
• Simple Single-Loop Control Design
- Voltage-Mode PWM Control
• Fast Transient Response
- High-Bandwidth Error Amplifier
- Full 0% to 100% Duty Ratio
The output voltage of the converter can be precisely
regulated to as low as 1.27V, with a maximum tolerance of
±1.5% over temperature and line voltage variations.
• Excellent Output Voltage Regulation
- 1.27V Internal Reference
- ±1.5% Over Line Voltage and Temperature
The HIP6012 provides simple, single feedback loop, voltage-
mode control with fast transient response. It includes a
200kHz free-running triangle-wave oscillator that is
adjustable from below 50kHz to over 1MHz. 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 ratio
ranges from 0% to 100%.
• Overcurrent Fault Monitor
- Does Not Require Extra Current Sensing Element
- Uses MOSFETs r
DS(ON)
• Small Converter Size
- Constant Frequency Operation
- 200kHz Free-Running Oscillator Programmable from
50kHz to Over 1MHz
The HIP6012 protects against overcurrent conditions by
inhibiting PWM operation. The HIP6012 monitors the current
• 14 Pin, SOIC and TSSOP Packages
• Pb-Free Available (RoHS Compliant)
by using the r
of the upper MOSFET which eliminates
DS(ON)
the need for a current sensing resistor.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
