LM2853MHX-3.3

The LM2853MHX-3.3 is a voltage regulator from Texas Instruments. It is a push-pull DC-DC switching regulator that operates at an input voltage range of 3.0V to 5.5V and provides a regulated output voltage of 3.3V. It offers an integrated pull-up resistor, which eliminates the need for an external MOSFET-driver circuit or external resistor to achieve the pull-up function for the high-side MOSFET. This integrated solution provides increased efficiency and minimized component count.

The LM2853MHX-3.3 uses a synchronous rectification buck-boost converter topology. It consists of two internal power MOSFETs (one high-side and one low-side) and two outputs (a positive output and a negative output) with drive current capability of up to 1A for the positive output and up to 0.1A for the negative output. The device includes an internal pulse-width modulation (PWM) controller and a current-mode loop, which provides improved line and load transient response.

The LM2853MHX-3.3 has over-voltage and under-voltage protection features that protect the device from output over-voltage, under-voltage and over-current conditions. This device also features a single-stage voltage-hopping feature that allows the device to function as a DC-DC converter with wide input voltage range. The device also has a low-power sleep mode, which reduces power consumption and increases the efficiency of the output voltage regulation.

The LM2853MHX-3.3 is suitable for a wide range of applications such as LED lighting, battery-powered systems, point-of-load (PoL) regulators, power supplies for automotive and portable electronics, gaming consoles and other consumer electronic devices. It can also be used for industrial equipment and telecom infrastructure.

The LM2853MHX-3.3 is an ideal solution for designs that require a compact, cost-effective, reliable and efficient voltage regulator. It is available in a low-profile 10-pin micro package with a maximum operating temperature of 125°C.
