PMIC – Voltage Regulators – DC DC Switching Regulators
The MAX20003CATPD/V+T is a high-frequency synchronous buck converter (DC-DC Step Down) delivering up to 3A continuous output current in a very small footprint. The converter offers configurable switching and output voltage sequencing, ultrafast transient response, and integrated features such as a low-power sleep mode. An internal power switch (FET) and integrated gate drivers facilitate a simple, compact design.
Application Field and Working Principle
The MAX20003CATPD/V+T is ideally suited for applications requiring high conversion efficiency and a wide input voltage range, such as mobile phone power management, battery stack voltage regulation and power supply for SoC core rails, FPGAs and more. The external(FET) and integrated gate drivers integrated with smart features facilitate a compact design.
The DC-DC converter works by first converting the input voltage to a certain reference voltage. Then, it chops the reference voltage to provide a stream of pulses, at the frequency and duty cycle determined by the feedback signals. The converter then reassembles the chopped reference voltage and converts it back to output voltage, according to the feedback voltage.
The efficient synchronous buck topology is based on a buck-converter-like structure, which implies that the voltage drop across the two switches (high/low side) is nearly equal. Moreover,it provides high step-down ratios and fast transient responses in addition to a wide input voltage range. This topology provides a seamless transition between the switching on and off of the high-side and low-side FETs, thus resulting in reduced current ripple.
Features
The MAX20003CATPD/V+T has a wide input voltage range of 4V to 20V. Its low quiescent current of 5.5mA and high efficiency of up to 94% make it an excellent candidate for power management in mobile applications. The output voltage can be adjusted through an externally connected DAC (VOUT) or adjusted using an internal preset reference. Maximum switching frequency of the device is 2.25MHz, making a very compact solution.
The MAX20003CATPD/V+T has several features to further improve system efficiency. Spread Spectrum frequency modulation (SSFM) helps to reduce EMI without the need for external components. In addition, the device has Cycle by Cycle current limit and hiccup mode overcurrent protection, thermal shutdown and under-voltage lockout (UVLO). The device also offers configurable switching rate response during load transients, as well as optional sequencing of the output voltages for smooth transition when multiple rails are required.
Conclusion
The MAX20003CATPD/V+T is an advanced synchronous buck converter DC-DC Step Down, specially designed for power management needs in mobile applications. Its features such as high efficiency and wide input voltage range, along with its current limit, overcurrent protection and thermal shutdown, make it an ideal solution for highly efficient applications.
