MAX730 Maxim, MAX730 Datasheet - Page 5

• Manufacturer Part Number: MAX730
• Description: 5V / Step-Down / Current-Mode PWM DC-DC Converters
• Manufacturer: Maxim

(Circuit of Figure 3, T
Note 3: Commercial temperature range external component values in Table 3.
Note 4: Wide temperature range external component values in Table 3.
Note 5: Standby and shutdown current includes all external component leakage currents. Capacitor leakage currents dominate at T
Note 6: Operation beyond the specifications listed in the electrical characteristics may exceed the power dissipation ratings of the device.
____________________________Typical Operating Characteristics (continued)
Sanyo OS-CON capacitors were used.
