Application Fields of RT6202AHGSP

The RT6202AHGSP is an ideal choice for a variety of applications. It can be used in cellular handsets, MIDs, tablet PCs, portable media players, power banks and white goods.

It is also suitable for other applications such as battery-powered equipment, power management for portable electronic devices and applications that require output voltage control.

The RT6202AHGSP is designed to provide ultra-small, low no-load quiescent current and fast transient response. It also provides high efficiency, excellent thermal performance and low EMI/RFI.

Working Principle of RT6202AHGSP

The RT6202AHGSP is a DC to DC switching regulator based on buck topology. It is based on an improved monolithic synchronous buck converter comprised of N- and P-channel Mosfets of 60mΩ and 10mΩ in the high side and low side switch respectively. This ensures a no-load quiescent current of 30μA.

The RT6202AHGSP provides output voltage stabilization during load transients and fast transient response. It operates from an input voltage range of 2.5V – 6V, while providing an adjustable output voltage range of 0.6V to 4.2V. It also has an integrated 5A current limited output switch.

The RT6202AHGSP has a maximum operating frequency of 1MHz and supports a programmable soft-start time of 5ms or 40ms. It has an operating temperature range of -40°C to +105°C. It requires an external low-pass filter to limit the output ripple.

Conclusion

The RT6202AHGSP DC to DC switching regulator is a highly efficient and low-cost power management solution for mobile devices. It offers excellent performance with a no-load quiescent current of 30μA, input voltage range of 2.5V-6V, output voltage range of 0.6V-4.2V and an adjustable soft-start time of 5ms or 40ms. The RT6202AHGSP is suitable for a wide range of applications that require output voltage control.
