Power management integrated circuits, or PMICs, serve a wide range of applications and can be found in almost every electronic device. The TPS657201YFFR is a low-noise, high-current, rail-to-rail power management IC designed for applications such as battery-operated consumer electronics, IoT, and industrial applications. With its high efficiency, small form factor, and low power consumption, the TPS657201YFFR makes an ideal choice for a variety of power management systems.

The TPS657201YFFR features an integrated LDOs, switchers, and synchronous rectifiers, in a single package. It provides an adjustable output voltage that can range from 0.45V to 6.5V. It is especially useful in applications requiring low-noise voltage references. The TPS657201YFFR provides up to 4.5A of output current, making it well-suited for applications requiring a high output current. Additionally, the device can be configured to feature active discharge between cycles, controlled by the Active Discharge (DL2) pin.

The TPS657201YFFR’s low operating current and high efficiency make it ideal for energy-constrained applications such as IoT, consumer electronics, and industrial. With its low-noise, rail-to-rail output, the device can provide a stable supply voltage with only minimal power filtering. The device also features a wide operating temperature range, making it suitable for a variety of industrial applications.

The TPS657201YFFR operates on a fixed frequency PWM control scheme. A built-in transconductance voltage control loop drives the output voltage to the desired level. A resistor divider connected to the output of the device controls the output voltage. The device is also equipped with a wide soft-start interval, allowing it to start-up slowly while preventing over-shoot and/or excessive current draw.

The TPS657201YFFR features a wide range of safety features, including Over Current Protection (OCP), Under Voltage Lockout (UVLO), Thermal Shutdown (TSD) and Repeated Softstart (SS). The OCP limits the input current to the device by turning off the output if the current exceeds a certain threshold. The UVLO monitors the input voltage and disables the device if the voltage falls below a certain threshold. The TSD protects the device from Thermal Runaway by shutting off the output if the temperature exceeds a certain maximum value. The SS helps protect the device from excessive stress during the start-up phase of the device.

The TPS657201YFFR is an efficient and highly reliable power management IC, ideal for a wide range of applications. With its low-noise, high-current, rail-to-rail output and multiple safety features, it is one of the most versatile power management solutions available. Its adjustable output voltage, wide operating temperature range, and low-power consumption make it an ideal choice for energy-constrained applications.
