Applications
* 100% duty cycle provides low dropout operation, extending battery life in portable systems. Automatic Burst Mode operation further increases efficiency at light loads. Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The internal syn
