SQM48T20010-PDB0

DC-DC Converters are devices that convert an unchangeable direct current (DC) voltage into another voltage. SQM48T20010-PDB0 is a DC-DC Converter that can convert a wide range of input voltages into a clean, regulated output at a single or dual voltage. This Converter offers flexibility and can achieve efficiency over a wide range of power levels.

Application field And Working Principle

The SQM48T20010-PDB0 Converter is typically used for electrical systems such as laptops, netbooks, personal computers, battery powered device, televisions, radio receivers, microwave ovens, military electronics, and other such devices. This DC-DC Converter offers high efficiency, small size and a wide range of input voltages, making it suitable for a variety of applications.

The SQM48T20010-PDB0 is a synchronous, step-down DC-DC converter that utilizes a fixed frequency, constant on-time control architecture. It uses MOSFETs for the output stage, which enables the Converter to provide high efficiency and high transient response with very little auxiliary power. The output voltage of the Converter is controlled by an internal error amplifier that compares the feedback voltage to a reference voltage using a voltage divider. The feedback voltage is regulated at a fixed ratio to the input voltage.

The SQM48T20010-PDB0 Converter uses a pulse-width modulation (PWM) waveform to drive the MOSFETs at a constant frequency. The switching frequency is controlled by an on-chip oscillator. The MOSFETs are operated in a synchronous mode, so that the voltage and current are in phase with each other. The switching frequency can be changed by adjusting the on-chip oscillator, allowing for different efficiency levels and levels of transient response.

The SQM48T20010-PDB0 Converter also has a low-noise, low-dropout linear regulator on board. This linear regulator helps reduce the input noise and stabilize the output voltage. It also provides better thermal characteristics and lower power consumption than a simple buck converter.

The SQM48T20010-PDB0 Converter is a very efficient and reliable DC-DC Converter, and is designed to provide great stability and flexibility in a wide range of applications. Its low noise and low power consumption make it especially suitable for battery powered devices.
