RT8005 1A, 2MHz, High-Efficiency Synchronous Buck PWM Converter General Description The RT8005 is a high-efficiency synchronous buck PWM converter with integrated P-Channel and N-Channel power MOSFET switches. Capable of delivering 1A output 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 www.DataSheet4U.com device operates at 2MHz PWM switching fixed frequency, can use smaller CIN, COUT capacitor and inductor. The RT8005 integrates two low RDS(ON) 230mΩ and 180mΩ of high- and low-side switching MOSFETs to reduce board space, as only resistors and capacitors along with one inductor are required externally for operation.
