The TL5001IPG4 is a one-channel, wide-input range, internal synchronous MOSFET step-down DC-DC switching regulator controller. The device can operate over an input voltage range of 4.5V to 30V and has an adjustable output voltage down to 0.8V. The device does not require any external compensation components and has excellent transient performance. It also features adjustable operating frequency, current limit, and soft start, and can be driven by a single ended or complementary PWM input.

Application Field

The TL5001IPG4 is ideal for a wide range of applications including automotive, industrial, and consumer electronics. The device can be used in applications such as automotive backup cameras, industrial process control systems, and consumer electronics, such as mobile radios, DVD players, and portable electronics. The device is designed to provide efficient, low noise, and cost-effective power conversion, and has an adjustable operating frequency for powering digital circuits without compromising the noise performance.

Working Principle

The TL5001IPG4 operates according to hysteretic control principle, which is based on the idea of detection and comparison of the values of current and reference signals. The device operates in pulse-width modulation (PWM) mode and uses an internal slow-start circuit to minimize inrush current on start-up and reaches the required output voltage quickly and accurately. The built-in ramp compensation strategy prevents any overshoot or undershoot of the output voltage. The current limit is adjustable and the frequency is also adjustable up to 1MHz. The device has an integrated internalMOSFET thatallows it to handle up to 3A of continuous output current. The device also features a low noise, low ripple operation that can be selected in the input stage.

In summary, The TL5001IPG4 is a one-channel, wide-input range, internal synchronous MOSFET step-down DC-DC switching regulator controller. It operates over a 4.5V to 30V input voltage range and provides adjustable output voltage control down to 0.8V. Its hysteretic control principle offers excellent transient performance and adjustable operating frequency, current limit, and soft start. The device has integrated internal MOSFET for handling up to 3A of continuous output current with low noise and low ripple operation.
