■Standard circuit

The circuit can operate without Cin, but adding Cin to the circuit can lower the feed-

back noise to the Input; this method is also effective in improving efficiency because

input voltage drop during switching can be eased. Under the condition of Iout≤10mA,

please connect tantalum capacitor of 10μF to 47μF to a coil as close as possible.
