... ADP2300/ADP2301 APPLICATIONS INFORMATION PROGRAMMING THE OUTPUT VOLTAGE The output voltage of the ADP2300/ADP2301 is externally set by a resistive voltage divider from the output voltage to the FB pin, as shown in Figure 42. Suggested resistor values for the typical output voltage setting are listed in Table 6. The equation for the output voltage setting is ⎛ ...

... SW 100 1k The precision enable feature also allows the ADP2300/ADP2301 to be sequenced precisely by using a resistive voltage divider with another dc-to-dc output supply, as shown in Figure 47. With a 1.2 μA pull-down current on the EN pin, the equation for the start-up voltage in Figure 46 and Figure 47 is ...

... The high switching frequency of the ADP2300/ADP2301 allows the use of small inductors. For best performance, use inductor values between 2 μH and 10 μH for ADP2301, and use inductor values between 2 μH and 22 μH for ADP2300. The peak-to-peak inductor current ripple is calculated using the following equation: ⎛ ...

... In general, most applications using the ADP2301 (1.4 MHz 40 2 switching frequency) require a minimum output capacitor value μF, whereas most applications using the ADP2300 (700 kHz 40 2 switching frequency) require a minimum output capacitor value μF. Some recommended output capacitors for are listed in Table 9 ...

... ADP2300/ADP2301 THERMAL CONSIDERATIONS The ADP2300/ADP2301 store the value of the inductor current only during the on time of the internal MOSFET. Therefore, a small amount of power is dissipated inside the ADP2300/ADP2301 package, which reduces thermal constraints. However, when the application is operating under maximum load with high ambient temperature and high duty cycle, the ...
