Description
- The TPS65217 is a single-chip power management IC specifically designed to support applications in portable and 5-V non-portable applications. It provides a linear battery charger for single-cell Li-ion and Li-Polymer batteries, dual-input power path, three step-down converters, four LDOs, and a high-efficiency boost converter to power two strings of up to 10 LEDs each. The system can be supplied by any combination of USB port, 5-V AC adaptor, or Li-Ion battery. The device is characterized across a 40°C to +105°C temperature range which makes it suitable for industrial applications. Three high-efficiency 2.25-MHz step-down converters can providing the core voltage, memory, and I/O voltage for a system.
- These step-down converters enter a low power mode at light load for maximum efficiency across the widest possible range of load currents. For low-noise applications the devices can be forced into fixed frequency PWM using the I2C interface. The step-down converters allow the use of small inductors and capacitors to achieve a small solution size.
- LDO1 and LDO2 can support system-standby mode. In SLEEP state output current is limited to 1 mA to reduce quiescent current whereas in normal operation they can support up to 100 mA each. LDO3 and LDO4 can be configured to support up to 4 00 mA each and can be configured as load switches instead of regulators. All four LDOs have a wide input voltage range that allows them to be supplied either from one of the DC-DC converters or directly from the system voltage node.
- By default only LDO1 is always ON but any rail can be configured to remain up in SLEEP state. Especially the DC-DC converters can remain up in a low-power PFM mode to support system suspend mode.
- The TPS65217 offers configurable power-up and power-down sequencing and several housekeeping functions such as power-good output, pushbutton monitor, hardware reset function and temperature sensor to protect the battery.
- For details on specific applications please see our application note SLVU551.
- The TPS65217 comes in a 48-pin leadless package (6-mm × 6-mm QFN) with a 0.4-mm pitch.
