RT8003, High-Efficiency Synchronous Buck PWM Converter

The RT8003 is a high-efficiency synchronous buck PWM converter with integrated P-Channel and N-Channel power MOSFET switches.

Features

* include internal soft-start, chip enable, overtemperature and over-current protections. It is available in a space-saving VDFN-10L 3x3 package. Ordering Information RT8003 Package Type QV : VDFN-10L 3x3 (V-Type) Operating Temperature Range P : Pb Free with Commercial Standard Note : RichTek Pb

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 on
