General Description
AP2004 is an asynchronous PWM boost converter
using a constant frequency peak current mode. An
external Schottky diode is needed. At light load,
AP2004 works in the light load mode. The supply
current during the light mode is 100uA and less than
1uA in shutdown mode, together with the 130mΩ
internal NMOS power transistor guarantees high
efficiency in the whole output load current range. Up to
3A peak current, Let AP2004 can provide 1A output
load current, which is suitable to use as MID and
mobile power supply. The input voltage 2.5~5.5V.The
operating frequency is internally set at 1MHz.
The device is available in the small profile SOT23-6L
package.
