Регуляторы напряжения - Импульсные регуляторы TPS61088RHLT

Импульсный повышающий DC-DC стабилизатор , регулируемый, 2.7В-12В (Vin), 4.5В-12.6В, 10А, VQFN-20

The TPS61088RHLT is a high-power density fully integrated synchronous Boost Converter with 11mR power switch and a 13mR rectifier switch to provide a high efficiency and small size solution in portable systems. The TPS61088 has wide input voltage range from 2.7 to 12V to support applications with single cell or two cell Lithium batteries. The device has 10A switch current capability and is capable of providing an output voltage up to 12.6V. The TPS61088 uses adaptive constant OFF-time peak current control topology to regulate the output voltage. In moderate to heavy load condition, the TPS61088 works in the pulse width modulation (PWM) mode. In light load condition, the device has two operation modes selected by the MODE pin. One is the pulse frequency modulation (PFM) mode to improve the efficiency and another one is the forced PWM mode to avoid application problems caused by low switching frequency.

• Mode selection between PFM mode and forced PWM mode at light load
• Resistor-programmable switch peak current limit
• Programmable soft-start
• Output overvoltage protection at 13.2V
• Cycle-by-cycle overcurrent protection
• Thermal shutdown
• Up to 91% efficiency at VIN=3.3V, VOUT=9V and IOUT=3A
• 1µA Current into VIN pin during shutdown
• Green product and no Sb/Br
