Data sheet:
Certificate:
The TLV61290 provides a power supply solution for products powered by a nickel-rich, silicon anode, Li-ion or LiFePO4 battery. The voltage range is optimized for single-cell portable applications like in smart-phones or POS terminal.
Used as a high-power pre-regulator, the device extends the battery run-time and overcomes input current and voltage limitations of the powered system. With a wide input voltage range of 2.0V to 5.0V. Program the output voltage by I2C up to 5.0V, and the default output voltage is 3.4V.
During operation, when the battery is in a good state of charge, the TLV61290 will work in bypass mode, connecting the battery to the power supply system through the bypass FET. If the battery gets to a lower state of charge and its voltage becomes lower than the desired minimum system voltage, the device seamlessly transits into boost mode to use the full battery capacity.
The TLV61290 offers a very small solution size with 16-ball YBG package.
- Wide VIN range from 2.0V to 5.0V
- Start up input voltage: 2.2V
- Programmable average input current limit (3.5A to 8A) via I2C
- Programmable output voltage (2.35V to 5.0V) via I2C, default 3.4V
- 97.99% efficiency at VIN = 3.3V, VOUT = 3.4V, IOUT = 1A
- 95.73% efficiency at VIN = 3.3V, VOUT = 3.4V, IOUT = 3A
- <300mV undershoot at VIN = 2.7V, VOUT = 3.4V, IOUT = 0A → 3A (0.2A/µs slew rate)
- Integrated bypass MOSFET (10mΩ), high-side MOSFET (10mΩ), low-side MOSFET (10mΩ)
- Auto bypass mode when VIN > VOUT
- Programmable auto PFM operation, Forced PWM operation or Ultrasonic mode operation (avoid audio band noise) during light load condition
- Spread spectrum modulation and EMI improvement
- Output discharge function when EN logic is low
- True disconnection between input and output during shutdown
- Thermal shutdown and over current protection
- I2C compatible I/F up to 1Mbps
- 1.2V I/O logic control interface
- 16-ball WCSP package
