SNVS884B –AUGUST 2012–REVISED MAY 2013  
LM10502 Dual Buck + LDO Power Management Unit  
Check for Samples: LM10502  
1
FEATURES  
DESCRIPTION  
The LM10502 are advanced PMUs each containing  
two configurable, high-efficiency buck regulators for  
supplying variable voltages. The device is ideal for  
supporting ASIC and SOC designs for Solid-State  
and Flash drives.

•
Two Highly Efficient Programmable Buck  
Regulators  
–
–
Integrated FETs with Low RDSON  
Bucks Operate with Their Phases Shifted to  
Reduce the Input Current Ripple and  
Capacitor Size  
The LM10502 operate cooperatively with the  
application ASIC to optimize the supply voltage for  
low-power conditions and Power Saving modes via  
the SPI interface. It also supports a 250 mA LDO and  
a programmable Interrupt Comparator to monitor VIN.  
–
Programmable Output Voltage via the SPI  
interface

–
Overvoltage and Undervoltage Lockout  
Automatic Internal Soft Start with Power-on  
Reset  
–
–
Current Overload and Thermal Shutdown  
Protection  
PFM Mode for Low-Load, High-Efficiency  
Operation  
•
•
Low-Dropout LDO 3.0V, 250 mA  
SPI-Programmable Interrupt Comparator (2.0V  
to 4.0V) to Monitor VIN  
APPLICATIONS  
•
Solid-State Drives  
KEY SPECIFICATIONS
