The HIP6004DCB from Intersil is a Buck and Synchronous-Rectifier PWM Controller and Output Voltage Monitor, optimized for high-performance microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronous-rectified buck topology, integrating control, output adjustment, monitoring, and protection functions into a single package.
The output voltage is adjustable from 1.1VDC to 1.85VDC in 25mV increments via a TTL-compatible 5-bit DAC. The voltage-mode PWM control with a fast transient response is achieved through a high-bandwidth error amplifier and a programmable 200kHz oscillator, adjustable from 50kHz to over 1MHz. The output voltage is precisely regulated to within ±1% over temperature and line voltage variations.
Protection features include over-current and over-voltage monitoring, which inhibit PWM operation. An additional overvoltage protection triggers an external SCR to crowbar the input supply. Current is monitored using the MOSFET's rDS(ON), eliminating the need for a separate sensing resistor. The device also includes a Power-Good output signal when the output voltage is within ±10% of the DAC setting.
This controller operates from a +5V or +12V input and is available in a 20-lead SOIC package. Its design facilitates small converter sizes and offers full 0% to 100% duty ratio operation.
