Регуляторы напряжения - Импульсные регуляторы TPS61092RSAR

Синхронный повышающий импульсный стабилизатор , фиксированный, 1.8В-5.5В (Vin), 5В и 2А, QFN-16

The TPS61092RSAR is a Boost Converter provides a power supply solution for products powered by either one-cell li-ion or li-polymer or a two-cell alkaline, NiCd or NiMH battery and required supply currents up to or higher than 1A. The converter generates a stable output voltage that is either adjusted by an external resistor divider or fixed internally on the chip. It provides high efficient power conversion and is capable of delivering output currents up to 0.5A at 5V at a supply voltage down to 1.8V. The implemented boost converter is based on a fixed frequency, pulse-width- modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency. Boost switch and rectifier switch are connected internally to provide the lowest leakage inductance and best EMI behaviour possible. The maximum peak current in the boost switch is limited to a value of 2500mA. The converter can be disabled to minimize battery drain.

• Power save mode for improved efficiency at low output power
• Low battery comparator
• Low EMI-converter (integrated antiringing switch)
• Load disconnect during shutdown
• Over-temperature protection
