.ti. SNVS884B - AUGUST 2012 - REVISED MAY 2013 LM10502 Dual Buck + LDO Power Management Unit Check for Samples: LM10502 Features - 2 Two Highly Efficient Programmable Buck Regulators - 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 - Low-Dropout LDO 3.0V, 250 m A - SPI-Programmable Interrupt parator (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 m A LDO and a programmable Interrupt parator to monitor VIN. APPLICATIONS - Solid-State Drives KEY SPECIFICATIONS - LM10502 - Programmable Buck Regulators: - Buck 1: 1.1V to 3.6V; 1A - Buck 2: 0.7V to 1.335V; 1A - ±3% Feedback Voltage Accuracy - Up to 95% Efficient Buck Regulators - 2MHz Switching Frequency for...
