L4931ABD25

The L4931ABD25 is an abosorptively mode buck and boost regulator with an adjustable output voltage which can go lower than or higher than the input voltage, providing a highly efficient, low-noise power supply. This device is constructed of P-channel and N-channel MOSFETs, which offer high switching speeds, low on-resistance, and low heat dissipation even when working at high switching frequency. The L4931ABD25 is made up of two fixed frequency dc-dc converters, a buck and a boost, that run at the same frequency, but with different independently adjustable duty cycles. The output voltage can be adjusted between 0.9V and 5.5V, while the input voltage can range from +2.5V to +18V. Thanks to the integrated circuits, this device can be used in a variety of applications with the same basic components in order to power nearly any type of electronic circuit.

The L4931ABD25 is an ideal regulator for applications that require current or power management in a low noise, low power consumption, space-conscious design. It is suitable for powering ARM microcontrollers, microprocessors, FPGAs, DDR memories, and other low-power applications. The device is capable of providing controlled shutdown, while its high switching frequency of 1.2MHz enables fast transient response with minimal output voltage deviation. In addition, its low-dropout (LDO) mode provides an ideal combination of power performance for battery-powered systems.

The L4931ABD25 includes an overvoltage protection (OVP) for inrush current and an overcurrent protection (OCP) for fault tolerance. Its over-temperature protection (OTP) feature ensures safe operation in thermal tests. In order to regulate the output voltage of the device, a control circuit is used. With the adjustable output voltage and the enable input, the output voltage is adjusted to the correct value and the enable input is used to set the maximum current.
