LM10504 Smallest Integrated PMIC for SSDs Overview

Bob demonstrates the LM10504, the industry’s smallest (2.8 x 2.8 mm) fully integrated PMIC/PMU for solid state drives (SSDs). This triple buck+LDO solution features:

• Industry’s smallest SSD PMIC at 2.8 x 2.8 mm
• Programmable buck regulators (up to 95% efficiency) + LDO:
• Buck 1: 1.1V to 3.6V; 1.6A
• Buck 2: 1.1V to 3.6V; 1A
• Buck 3: 0.7V to 1.335V; 1A
• LDO: 3.0V, 250 mA
• Integrated FETs with low RDSON
• 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
• Power-down data protection enhances data integrity
