HIP6302CBZ-T Application Field and Working Principle

HIP6302CBZ-T is a high efficiency, low-noise, low-ripple, space-saving switch-mode power converter optimized for use as a DC/DC switching controller for applications requiring high power and demanding miniaturization. It is one of the Voltage Regulators from DC/DC Switching Controllers classification from PMIC (Power Management Integrated Circuits).

Application Field

HIP6302CBZ-T DC/DC switching controller can be used in a wide range of applications. For example, notebook computer power systems, smart phone/ handset systems, server and telecom/datacom systems, etc. Its small package size gives it an edge where high power, small size, robustness, and optimized conduction losses are desired.

Working Principle

The HIP6302CBZ-T DC/DC switching controller is a non-sync Buck-Boost controller with input voltage range of 5V to 12V, and output voltage range of 0.5V to VIN. It has a single comprehensive control loop, pre-programmed with standard integer values that can be adjusted. It is also compatible with external synchronous MOSFETs for higher efficiency.

The working principle of the HIP6302CBZ-T DC/DC switching controller is based on two modes - forced current mode and voltage mode. In voltage mode, the voltage at the IC’s output is regulated through a comparator, while in the on-time forced current mode, the output current is regulated by measuring the on time of the external MOSFETs.

The internal PWM (Pulse Width Modulation) oscillator is adjustable up to a frequency of 700kHz. The stability of the loop is determined by an integrated current-limited soft-start and voltage-limited soft-stop. The controller also provides protection from overload and over-temperature conditions.

Conclusion

HIP6302CBZ-T DC/DC switching controller from PMIC’s Voltage Regulators from DC/DC Switching Controllers can be used in a wide range of high power applications such as notebook computers and servers. Its small size and high efficiency give it an edge over most competing products. It works on the principle of voltage mode and on-time forced current mode, and has an adjustable oscillator frequency of up to 700kHz. It also provides protection from overload and over-temperature.
