The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help reduce input ripple and improve transient response.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor value (at least 10uF), and keep the input and output capacitors close to the IC. Additionally, ensure that the input voltage is within the recommended range and the output current is within the specified limits.
The MAX860ISA+ can handle input voltages up to 28V, but it's recommended to operate within the specified input voltage range of 4.5V to 24V for optimal performance and reliability.
The MAX860ISA+ is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation. Consult the datasheet for specific derating guidelines.
The output voltage of the MAX860ISA+ is adjustable using the FB (feedback) pin. The output voltage can be calculated using the formula: Vout = 1.25V x (R1/R2 + 1), where R1 and R2 are the resistors connected to the FB pin.
