Buck and Synchronous-Rectiﬁer (PWM)

Controller and Output Voltage Monitor

Features

• Drives Two N-Channel MOSFETs

• Operates from +5V or +12V Input

The HIP6014 provides complete control and protection for a

DC-DC converter optimized for high-performance

• Simple Single-Loop Control Design

- Voltage-Mode PWM Control

microprocessor applications. It is designed to drive two

N-Channel MOSFETs in a synchronous-rectified buck topology.

The HIP6014 integrates all of the control, output adjustment,

monitoring and protection functions into a single package.

• Fast Transient Response

- High-Bandwidth Error Ampliﬁer

- Full 0% to 100% Duty Ratio

The output voltage of the converter is easily adjusted and

precisely regulated. The HIP6014 includes a fully TTL-

compatible 5-input digital-to-analog converter (DAC) that

increments and from 1.8V

The precision reference and voltage-mode regulator hold the

selected output voltage to within ±1% over temperature and

line voltage variations.

The HIP6014 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%.

The HIP6014 monitors the output voltage with a window

comparator that tracks the DAC output and issues a Power

Good signal when the output is within ±10%. The HIP6014

protects against over-current and over-voltage conditions by

inhibiting PWM operation. Additional built-in over-voltage

protection triggers an external SCR to crowbar the input

supply. The HIP6014 monitors the current by using the
