The UCC2541PWPG4 belongs to the Texas InstrumentsTM family of DC-DC switching controllers. This controller integrates a pulse-width modulated (PWM) voltage regulator, voltage feedback deployment, programmable over-voltage, under-voltage and thermal protection. It also has adjustable dead-time control and a Soft-Start feature. This DC-DC switching controller works by delivering a round of pulses with the programmed width to control a power transistor switch “on” state voltage and current bias. It is well suited to applications requiring high precision and wide operating range, such as telecom power supplies, industrial power supplies, and battery chargers.

The UCC2541PWPG4 supports a wide range of input and output voltages, from 0.7 Vdc to 5.5 Vdc for its inputs and from 0.7 Vdc to 24 Vdc for its outputs. It also offers a wide control range with adjustable dead-time and switching frequency, from 200 kHz to 2.4 MHz. This makes the UCC2541PWPG4 suitable for applications requiring either high-efficiency or high-output power levels. The UCC2541PWPG4 provides tight regulation of the output voltage even under varying input voltage and load conditions.

In addition to its wide range of input and output voltages, the UCC2541PWPG4 provides a variety of other features not found in many other voltage controllers. It includes adjustable frequency and dead-time control, voltage loop response management, over-voltage, under-voltage and thermal protection, internal 4 MHz oscillator, shutdown latch, soft-start, and a sleep mode. The UCC2541PWPG4 can operate in either a voltage mode or a current mode, allowing for fast transient response and optimal regulation. In addition, it provides a low-noise design for applications that require noise-free operation.

The UCC2541PWPG4 is ideal for power supply applications requiring fast transient response, high efficiency, and noise-free operation, such as telecom power supplies, industrial power supplies, and battery chargers. It is also an excellent choice for applications requiring wide operating ranges, adjustable dead-time, voltage loop response management and over-voltage, over-current, and thermal protection. With its wide operating range and excellent transient response, the UCC2541PWPG4 is an ideal choice for power supply designs.
