產品總覽
The TPS65217DRSLT is a single-chip Power Management IC specifically designed to support applications in portable and 5V 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, 5VAC adaptor or Li-Ion battery. The device is characterized across a -40 to +105°C temperature range. Three high-efficiency 2.25MHz step-down converters can provide the core voltage, memory and I/O voltage for a system. This step-down converter enters 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.
- Charger/power path - 2A output current on power path
- Charger/power path - 20V tolerant USB and AC inputs
- Charger/power path - thermal regulation, safety timers
- Charger/power path - temperature sense input
- Step-down converter (DCDC1, 2, 3) - Three step-down converters with integrated switching FETs
- Step-down converter (DCDC1, 2, 3) - Power save mode at light load current
- Step-down converter (DCDC1, 2, 3) - 100% duty cycle for lowest dropout
- Step-down converter (DCDC1, 2, 3) - Passive discharge to ground when disabled
- LDOs (LDO1, 2) - two adjustable LDOs
- LDOs (LDO1, 2) - LD02 can be configured to track DCDC3
- LDOs (LDO1, 2) - typical 15pA quiescent current
- Load switches (LDO3, 4) - two independent load switches that can be configured as LDOs
- WLED driver - Internally generated PWM for dimming control
- WLED driver - supports two strings of up to 10 LEDs at 25mA each
- WLED driver - Internal low-side current sinks
- Protection - Undervoltage lockout and battery fault comparator
- Protection - Always-on push-button monitor
- Protection - Hardware reset pin
- Interface - password protected I2C registers
