Product details
Overview
TPS65720YFFR from Texas Instruments is a highly integrated power management IC (PMIC) for portable Li-ion battery-powered systems, featuring a 300-mA battery charger with power path management, a 200-mA step-down DC-DC converter (VDCDC1 = 2.05 V default), a 200-mA LDO (VLDO1 = 1.85 V default), I²C interface, and four GPIOs. It operates from 2.3 V to 5.6 V input and delivers up to 92% efficiency at 2.25 MHz switching frequency.
For engineers reviewing the TPS65720YFFR datasheet, TPS65720YFFR pinout, TPS65720YFFR application, or TPS65720YFFR equivalent, key selection considerations include its 25-ball DSBGA (YFF) package, power path behavior under AC/battery source arbitration, programmable charge current via ISET resistor, and reset generation triggered by LDO1 undervoltage (–7% to –13% tolerance).
Technical Context
The TPS65720YFFR integrates a USB-friendly linear battery charger with automatic power path selection between AC adapter and battery, enabling seamless system power-up even during charging. Its DC-DC converter uses a fixed 2.25-MHz PWM architecture with automatic transition to PFM mode at light load to maximize efficiency across 0–200 mA output range.
Control is implemented via an I²C-compatible interface with factory-programmed nonvolatile registers, supporting configuration of charge current, DC-DC/LDO output voltages (where externally adjustable), power-on hold logic, and interrupt masking. The device includes thermal shutdown (150°C), undervoltage lockout (2.2 V on SYS), and battery temperature monitoring via NTC-connected TS pin.

Equivalent & Alternatives
The following parts are listed as comparable options for similar power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS657201YFFT | Same YFF package; includes TS_OUT analog multiplexer for battery voltage/temperature reporting; 500-mA AC input limit. | Required when system needs battery telemetry (VBAT/TS) over single pin; not suitable if only basic charging is needed. | Select TPS657201YFFT when integrating fuel-gauge algorithms or thermal throttling based on real-time battery data. |

FAQ
What is the default output voltage of the DC-DC converter in TPS65720YFFR?
The TPS65720YFFR has an externally adjustable DC-DC converter; its default output voltage is 2.05 V, set by internal feedback resistors. This value is confirmed in the Typical Application Schematic and Electrical Characteristics table of the SLVS979C datasheet. Designers may modify VDCDC1 using an external resistor divider on FB_DCDC1, where the internal reference is 0.6 V.
Does TPS65720YFFR support battery temperature monitoring?
Yes, TPS65720YFFR supports battery temperature monitoring via the TS pin, which accepts a thermistor (e.g., 10 kΩ NTC) connected to GND. The device measures thermistor voltage to derive temperature, with full-scale input range of 0–1.4 V corresponding to –20°C to +60°C. This function is fully operational in the YFF package and does not require TS_OUT multiplexing (unlike TPS657201/TPS657202).
What package type and dimensions does TPS65720YFFR use?
TPS65720YFFR uses a 25-ball wafer chip scale package (DSBGA) with designation YFF, measuring 2.11 mm × 2.11 mm nominal body size and 0.4-mm ball pitch. This package is explicitly listed in TI's Device Information table and Mechanical, Packaging, and Orderable Information section. It is distinct from the 32-pin WQFN (RSN) used by TPS65721.
How is the charge current programmed on TPS65720YFFR?
The charge current on TPS65720YFFR is programmed using an external resistor connected between the ISET pin and GND. The relationship is RISET = 1200 / ICHG, where R is in kΩ and ICHG is in mA. For the standard 300-mA fast charge, a 4.0-kΩ resistor is used. This method is specified in the Electrical Characteristics table and Functional Block Diagram sections of the datasheet.
What is the purpose of the HOLD_DCDC1 and HOLD_LDO1 pins on TPS65720YFFR?
HOLD_DCDC1 and HOLD_LDO1 are active-high inputs that maintain DCDC1 and LDO1 enabled after the PB_IN push-button signal is released. When pulled HIGH (e.g., by MCU GPIO or RC circuit), they override the default auto-shutdown behavior, allowing sustained power delivery during system wake-up or firmware initialization. Their function is documented in the Pin Functions table for the YFF package.
