FEATURES
1
•2 Two Highly Efficient Programmable Buck
Regulators
– Integrated FETs with Low R_DSON
– Bucks Operate with Their Phases Shifted to
Reduce the Input Current Ripple and
Capacitor Size
– 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
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.
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.
