TI TPS65132BYFFR

The TPS65132 series is designed to support positive/negative drive applications. Both outputs of the device use a single-inductor solution, providing users with the most compact solution while simplifying the bill of materials and maintaining high efficiency. The device can provide optimal line and load regulation capabilities under low-noise conditions. With an input voltage range of 2.5V to 5.5V, the device is optimized for products powered by single-cell batteries (lithium-ion batteries, lithium-nickel batteries, and lithium-polymer batteries) and power rails with fixed voltages of 3.3V and 5V. Output current options of 80mA and 150mA are available and can be programmed to 40mA. Two package options, CSP and QFN, are provided.
