Description:The ISL8240M is a fully-encapsulated step-down switching power supply that can deliver up to 100W output power from a small 17mmx17mm PCB footprint. The two 20A outputs may be used independently or combined to deliver a single output of 40A. Designing a high-performance board-mounted power supply has never been simpler -- only a few external components are needed to create a very dense and reliable power solution. 1. 5% output voltage accuracy, differential remote voltage sensing and fast transient response
The ISL8240MIRZ can handle input voltages up to 28V, but it's recommended to operate within the specified input voltage range of 7V to 24V for optimal performance and reliability.
To ensure the stability of the output voltage, it's essential to follow the recommended layout guidelines, use a sufficient output capacitor, and ensure that the input voltage is within the specified range. Additionally, the output voltage can be adjusted using the FB pin, and the output voltage tolerance can be set using the EN pin.
The ISL8240MIRZ can provide a maximum output current of 4A, but it's recommended to operate within the specified output current range of 0.5A to 3A for optimal performance and reliability.
To protect the ISL8240MIRZ from overheating, it's essential to ensure good thermal design, use a sufficient heat sink, and operate within the specified temperature range of -40°C to 125°C. Additionally, the device has built-in thermal protection that will shut down the device if the junction temperature exceeds 150°C.
The EN pin is an enable input that allows the user to turn the device on or off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. This pin can be used to implement power sequencing, shutdown, or low-power modes.
