TLV61220DBVR is a synchronous DC-DC type switching regulator controller optimized for PFM and PWM applications. This integrated circuit offers many features and can be used to design a power regulation system with a wide variety of voltage level settings. It is one of the most efficient regulators available, with a very low quiescent current, and can provide an output current up to 1A.

The TLV61220DBVR can be unique for powering low power applications such as medical equipment, industrial appliances, telecommunications, etc. It is also an excellent choice for power-sensitive applications due to its excellent power conversion performance and high efficiency. It operates in both battery-operated and AC wall adapter applications.

The TLV61220DBVR has two main modes of operation, Low Voltage PFM and High Voltage PWM. Low Voltage PFM is suitable for power regulation systems where the output voltage needs to be below 1.2V. The system operates in voltage-mode, which means that it is optimized for a single output voltage. The output voltage can be set using external resistors. High Voltage PWM mode is suitable for power regulation systems with an output voltage higher than 1.2V. It operates in current-mode and can provide an adjustable output current up to 1A. The output current is adjusted by changing an external resistor. This is an useful feature for applications such as lighting or motor control.

The TLV61220DBVR has a wide range of features. It includes under-voltage lockout (UVLO) and foldback protection features and has an adjustable switching frequency up to 500kHz. It also contains a power switch output and is equipped with an internal charge pump, allowing the system to start up with a low input source voltage. The TLV61220DBVR has excellent EMI performance, due to the inclusion of Spread Spectrum and an adjustable spread spectrum frequency.

The TLV61220DBVR application field is wide and the working principle is straightforward. It is a switching regulator which operates in either voltage-mode or current-mode. The system is optimized for a single voltage setting or adjustable output current. It has extra features such as UVLO protection and foldback protection. The TLV61220DBVR has excellent EMI performance and can provide an adjustable switching frequency up to 500kHz. It is ideal for powering low power applications in a wide range of sectors, from medical equipment to telecommunications.
