詳細說明
The TPS62110RSAR is a robust DC-DC converter designed to deliver efficient power management solutions for systems powered by 2- to 4-cell Li-ion batteries or 12-V/15-V rails. Featuring integrated N- and P-channel power MOSFET switches, this converter utilizes synchronous rectification to enhance efficiency and streamline the design by reducing external component requirements. By seamlessly transitioning to a power-saving PFM mode at light loads, the TPS62110RSAR optimizes energy consumption across a broad load current spectrum. Operating at a frequency of 1 MHz, the converter supports the use of compact inductors and capacitors, allowing for a more streamlined design. Additionally, the TPS62110RSAR can be synchronized to an external clock signal within the 0.8 MHz to 1.4 MHz range for enhanced flexibility. In shutdown mode, the converter draws less than 2 µA of current, ensuring minimal power usage. With a wide operating temperature range of -40°C to 85°C and a compact 16-pin VQFN package, the TPS62110RSAR is a versatile and reliable choice for power management applications
