The HIP6303CB-T is comes in a 6-pin SOT-23 package making it an ideal choice for smaller consumer electronic devices.

Application Field:

The HIP6303CB-T device is primarily intended for wide input voltage buck and boost applications such as digital TVs, portable devices and battery powered applications. The device is capable of delivering up to 700mA of output current and supports up to a 4.5V input voltage range making it suitable for a variety of applications. The device is capable of providing fast transient response and high efficiency along with low output noise to ensure the best performance of the application. The device is equipped with an integrated Low Noise PWM controller, a bootstrap circuit and an output over-current detection feature.

Working Principle:

The HIP6303CB-T device is a DC-DC switching controller designed to provide high efficiency and low noise operation. The device works by switching a MOSFET on and off based on the current load and the feedback voltage. The PWM controller is used to generate a fixed switching frequency and to adjust the ON time of the MOSFET. During the ON time, the output voltage is regulated through a voltage feedback loop with a reference voltage as the base. During the OFF time, the MOSFET is turned off and the inductor discharges energy to maintain the output voltage. When the load is low, the device works with hysteretic mode at lower frequency. This helps reduce the ripple and noise at the output. In addition, the device also has a bootstrap circuit which helps lower the total power losses.

The device is also equipped with output over-current protection (OCP) feature which helps prevent any damage to the device caused by excessive current. The OCP feature helps to keep the switching current within the rated value and prevents the MOSFET from getting damaged due to overcurrent.

The HIP6303CB-T device is an ideal solution for applications requiring a low noise, high performance and cost efficient voltage regulator. The integrated features such as the PWM controller, low noise operation, output over-current protection, and fast transient response make the device suitable for various consumer electronics devices.
