LOW-POWER BATTERY BACKUP IC  
WITH INTEGRATED BOOST CONVERTER  
1
FEATURES  
DESCRIPTION  
2
•
Power-Path Switch to Select Main Battery or  
Backup Battery for Real-Time Clock (RTC)  
The TPS65510 offers a suitable solution for power  
switch to select the main battery or the backup  
battery.  
•
Integrated Boost DC/DC Converter  
–
Modulation Select by Control Pin (PWMON),  
Pulse Frequency Modulation (PFM) or  
Pulse Width Modulation (PWM)  
This device automatically selects the power path. It  
depends on the voltage level of the VO_BT pin.  
When the main battery is removed, the power path of  
the VOUT pin is automatically changed from the  
output of 3.3-V low droppout (LDO) voltage regulator  
to the backup battery.  
–
–
–
Fixed Switching Frequency (PWM, 750 kHz)  
Peak Current Mode Control (PWM)  
Low Power Consumption (PFM)  
•
•
Four Integrated Low Dropout (LDO) Voltage  
Regulators for 1.2 V/1.8 V/3.3 V  
The backup battery is charged from the power path of  
the VRO pin (output of 3.3-V LDO) via an external  
diode and resistor. The input of the LDO voltage  
regulator comes from the internal boost converter.  
Two Integrated Indicators  
–
CS: Monitors the Voltage Level of Main  
Battery (VBAT) and Output voltage level of  
Boost Converter (VO_BT)  
The 1.2-V output LDO and 1.8-V output LDO voltage  
regulators have a enable pin, V_CTRL. If these  
outputs are not necessary, V_CTRL should be  
connected to AGND to save power consumption. The  
self-power consumption is less than 3 µA (maximum)  
using the backup battery.  
–
XRESET: Monitors the Output voltage Level  
of 3.3V LDO (VOUT)  
•
•
•
16-Pin QFN (3mm × 3mm) Package  
Operating Temperature –35°C to 85°C  
Protection  
This device has two indicators. One is CS, which  
monitors the voltage level of the VBAT pin and  
VO_BT pin. The other is XRESET, which monitors  
voltage level of the VOUT pin. These indicators  
should be connected to CPU/DSP to reset them.  
–
–
–
–
Overcurrent Protection (OCP)  
Overvoltage Protection (OVP)  
Thermal Shutdown (TSD)  
This device reduces the total solution area and  
extends the lifetime of the backup battery.  
Undervoltage Lockout (UVLO)  
APPLICATIONS  
•
Digital Still Cameras  
•
Portable Systems With Backup Battery
