LM10506
September 1, 2011
Triple Buck + LDO Power Management Unit
1.0 General Description
The LM10506 is an advanced PMU containing three config-
urable, 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 LM10506 operates cooperatively with ASIC to optimize
the supply voltage for low-power conditions and Power Sav-
ing modes via the SPI interface. It also supports a 100 mA
LDO and a programmable Interrupt Comparator.
2.0 Key Specifications
■ Programmable Buck Regulators:
— Buck 1: 1.1V to 3.6V; 1.3A
— Buck 2: 1.1V to 3.6V; 400 mA
— Buck 3: 0.7V to 1.335V; 600 mA
■ ±3% feedback voltage accuracy
■ Up to 95% efficient buck regulators
■ 2MHz switching frequency for smaller inductor size
■ 7 x 7 pin array 0.4 mm 34-bump micro SMD package
3.0 Features
■ Three 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
— Bypass mode available on Bucks 1 and 2
— PFM mode for low-load, high-efficiency operation
■ Low-dropout LDO 3.2V, 100 mA
■ SPI-programmable interrupt comparator (2.0V to 4.0V)
■ Alternate Buck V
OUTS selectable via H/L logic pins
■ RESET, STANDBY pins
4.0 Applications
■ Solid-State Drives
