HIP6020ACB-T

Overview

The HIP6020ACB-T is a synchronous-rectifier pulse-width modulator (PWM) controller designed for high-performance DC/DC conversion. It integrates a voltage-mode control architecture with an internal N-channel power MOSFET driver, eliminating the need for external Schottky diodes in buck applications. The device supports input voltages up to 15V and features adjustable switching frequencies. Key operational parameters include a fixed minimum on-time of 130ns and a programmable soft-start capability. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Feature Summary

• Integrates an internal N-channel pass FET for synchronous rectification
• Supports buck topology with integrated gate drive circuitry
• Features programmable soft-start to limit inrush current
• Includes undervoltage lockout and thermal shutdown protection

Applications

• Point-of-load (POL) voltage regulation modules
• High-density server and workstation power supplies
• Telecommunications intermediate bus converters
• Industrial equipment requiring efficient low-voltage distribution

Procurement Notes

Verify the specific suffix 'CB' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the operating environment remains within the specified -40°C to +85°C range. Confirm that the PCB layout accommodates the thermal requirements associated with the internal MOSFET integration. Cross-reference the ordering code with official Renesas or Intersil catalogs to avoid obsolete variants.

Selection Notes

Select this component when designing synchronous buck converters requiring high efficiency at moderate currents. The internal MOSFET simplifies the bill of materials compared to asynchronous designs using external diodes. Consider the maximum switching frequency limits and the required inductor selection based on the voltage-mode control characteristics. Evaluate the thermal dissipation capabilities of the SOIC package for the target application load.

Part Context

This part belongs to the HIP60xx series of PWM controllers from Intersil, now part of Renesas. These devices are engineered for desktop and notebook computer applications, specifically targeting CPU core voltage regulation. The family typically includes variants like the HIP6006 and HIP6012, differing primarily in current handling capabilities and feature sets such as dual-phase synchronization.

Replacement Considerations

Official cross-references may include the HIP6006CVZA-T or HIP6012CB-T depending on the specific current and phase requirements. Verify that any substitute maintains the same 8-pin SOIC footprint and compatible control logic levels.
