LM10506
SNVS729F – SEPTEMBER 2011 – REVISED AUGUST 2014
LM10506 Triple Buck + LDO Power Management Unit
1 Features
3 Description
The LM10506 is an advanced PMU containing three
1
Three Highly Efficient Programmable Buck
configurable,
high-efficiency
buck
regulators
for
Regulators
supplying variable voltages. The device is ideal for
Buck Regulator Outputs:
supporting ASIC and SOC designs for Solid-State
Buck 1: 1.1 V to 3.6 V; 1.3 A
and Flash drives.
Buck 2: 1.1 V to 3.6 V; 400 mA
The LM10506 operates cooperatively with ASIC to
optimize the supply voltage for low-power conditions
Buck 3: 0.7 V to 1.335 V; 600 mA
and Power Saving modes via the SPI interface. It
±3% Feedback Voltage Accuracy
also supports a 100-mA LDO and a programmable
Up to 95% Efficient Buck Regulators
Interrupt Comparator.
