ISL78233EVAL1Z

ISL78233EVAL1Z is an automotive synchronous buck regulator evaluation board. This evaluation board is used to demonstrate the performance of the ISL78233 low quiescent current, high-efficiency synchronous buck regulator. The evaluation board is intended for use by customers with requirements for point-of-load automotive applications with 2.7V to 5.5V input supply voltage, output voltages down to 0.8V and up to a 3A output current. The ISL78233EVAL1Z is used to evaluate the ISL78233 3mm x 3mm 16 lead TQFN package with a 1mm maximum height. The complete area that the regulator occupies can be as small as 0.22in².

• Synchronous buck regulator up to 95% efficiency
• 1% reference accuracy over temperature
• Resistor adjustable frequency from 500kHz to 4MHz, default set to 2MHz
• External synchronization from 1MHz to 4MHz
• 100ns maximum phase minimum on time allows wide output regulation operating at 2MHz
• Internal soft-start set to 1ms, adjustable with external soft-start capacitor
• Over-temperature, overcurrent, overvoltage, and negative overcurrent protection
