TPS62200EVM-211

TPS62200EVM-211, a 1-output, 3.3V synchronous buck converter, is a high-frequency, high-efficiency, low-profile, small footprint module aimed at providing power solutions for personal electronics, industrial, medical, and automotive applications. It is an evaluation module (EVM) designed for automotive-specific requirements, such as cold-crank conditions and Class B EMI compliance. This EVM operates on a single-voltage supply, such as a 3-6V battery, rechargeable cell, or other regulated voltage source.

The TPS62200EVM-211 works on the popular synchronous buck converter architecture, which consists of an internal high-side MOSFET and low-side MOSFET to regulate the current flowing from the input supply to the output. This type of switching regulator is ideal for applications where high power efficiency is required. The TPS62200EVM-211 operates with a punctual voltage accuracy of <1.2% and a current accuracy of <1.2%. Additionally, it features an adjustable soft-start capability for controlling inrush current, protection against thermal and current overload, and several other features.

The popular architecture also consists of a feedback loop that regulates the output voltage. The feedback loop consists of an internal error amplifier, an internal reference, and an output voltage feedback divider. The error amplifier compares the output voltage to the internally set reference voltage, which is 3.3V for the TPS62200EVM-211. If the output voltage differs from the set reference voltage, the error amplifier sends a signal to the PWM comparator to adjust the ratio between the high-side and low-side MOSFETs\' duty cycle to maintain the set output voltage.

The PWM comparator then amplifies the signal and switches the high-side and low-side MOSFETs on and off accordingly. The switching of the MOSFETs takes place at a switching frequency of 250kHz, which is ideal for minimizing switching losses and keeping the module hardware small. The module is capable of a maximum output current of 600mA.

In addition to using the TPS62200EVM-211 in automotive-specific applications, it is suitable for use in industrial, medical, communications, computing, point-of-load (POL), portable, automotive, and battery-powered applications that require high efficiency, quick transient response, and precise output voltage regulation. The TPS62200EVm-211 also features programmable under-voltage lockout (UVLO), short-circuit protection (SCP), and adjustable frequency to optimize the design for transient stability, output voltage accuracy, and minimum component size.

The TPS62200EVm-211 is an excellent option for designers looking for a high-efficiency, low-cost, and high-reliability solution for their applications. With its wide input voltage range, adjustable switching frequency, small footprint, and high efficiency, the TPS62200EVm-211 is well-suited for a variety of applications, ranging from automotive to portable and industrial.
