Power Management Unit 34-Pin Micro SMD T/R

The LM10506 is an advanced PMU containing three 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 LM10506 operates cooperatively with ASIC to optimize the supply voltage for low-power conditions and Power Saving modes via the SPI interface. It also supports a 100-mA LDO and a programmable Interrupt Comparator.

Three Highly Efficient Programmable Buck Regulators

• Buck Regulator Outputs:
  • Buck 1: 1.1 V to 3.6 V; 1.3 A
  • Buck 2: 1.1 V to 3.6 V; 400 mA
  • Buck 3: 0.7 V to 1.335 V; 600 mA
• ±3% Feedback Voltage Accuracy
• Up to 95% Efficient Buck Regulators
• 2MHz Switching Frequency for Smaller Inductor Size
• 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
• PFM Mode for Low-Load, High-Efficiency Operation
