The LM828M5/NOPB is a high-performance voltage regulator board used for DC-to-DC switching. It is commonly used for Automotive applications requiring a wide input voltage range and high output current. The device features fast transient response, low output noise, and high current output capability.

LM828M5/NOPB application field and working principle:

The primary application of the LM828M5/NOPB is in Automotive DC-DC switching applications, where high-current output is required and wide input voltage ranges are needed. The device utilizes a pair of power MOSFETs in a synchronous rectification configuration to provide high conversion efficiency and fast transient response. The device can be used to convert both positive and negative input voltages to an output which is either lower or higher than the input voltage. The output voltage can be adjusted by an external resistor connected to an internal adjustable voltage reference.

An internal undervoltage lockout (UVLO) feature can be enabled to protect the device against unwanted startup when the input voltage is too low. Additionally, the LM828M5/NOPB integrates a series of protection features such as over-voltage protection, current limitation, over-temperature protection, and input reverse polarity protection. The integrated protection circuitry ensures full safety and reliable operation even in harsh automotive environments.

The LM828M5/NOPB is a very efficient voltage regulator, with an efficiency of up to 96%. It provides a wide input voltage range and can effectively output up to 5A of current.

The device contains two high-side and two low-side power MOSFETs connected in a synchronous rectification configuration. This allows high conversion efficiency and fast transient response. The internal gain block is used to control the gate voltage on the MOSFETs, thus providing the desired output voltage.

The device is equipped with a voltage regulation control pin and an enable pin. The voltage regulation control pin can be used to set the output voltage via an external resistor. The enable pin can be used to start/stop the device. The device also has an internal, programmable, under-voltage lockout (UVLO) for protection against unwanted startup when the input voltage is too low.

The LM828M5/NOPB utilizes an advanced, low-noise signal control technique and operates with very low noise across the input and output voltage range. This makes the device highly suitable for Automotive applications which require a low noise operation and high output current capability.

The device also features an integrated short-circuit protection and over-temperature protection which ensures reliable and safe operation. Additionally, a unique, integrated dynamic current sharing circuitry is used to ensure that the device operates within its rated current capability.

The LM828M5/NOPB is an excellent choice for a wide range of Automotive applications which require high efficiency, fast transient response, low output noise, and high current output capability.
