RT8003 Datasheet Text
600mA, 2MHz, High-Efficiency Synchronous Buck PWM Converter
General Description
The RT8003 is a high-efficiency synchronous buck PWM converter with integrated P-Channel and N-Channel power MOSFET switches. Capable of delivering 600mA output current over a wide input voltage range of 2.4V to 5.5V, the RT8003 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.
The RT8003 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. The RT8003 has adjustable output range down to 0.5V. The other Features include internal soft-start, chip enable, overtemperature and over-current protections. It is available in a space-saving VDFN-10L 3x3 package.
