General Description
The RT8005 is a high-efficiency synchronous buck PWM converter with integrated P-Channel andN-Channel power MOSFET switches. Capable of delivering 1Aoutput current over a wide input voltage range of 2.4V to 5.5V, the RT8005 is ideally suited for portable applications powered by a single Li-Ion battery or by 3-cell NiMH/NiCd batteries. The device operates at 2MHz PWM switching fixed frequency, can use smaller CIN, COUT capacitor and inductor.
