CM3132-02SH Datasheet PDF - California Micro Devices Corp

Product Description
The CM3132 provides an integrated power solution for a CPU core and DDR-I memory for consumer and other embedded applications. It features three independent linear regulators for VCORE, VDDQ and VTT supply regulation. The default voltage for VCORE is 1.5V. The SENSE_CORE pin can be tied to GND for the default voltage, or through a resistor divider for setting the CPU core in the range 1.2V to 1.8V. VDDQ is internally set to 2.50V and the VTT voltage is always half the VDDQ voltage. A capacitor should be connected to each of the three outputs.

FEATUREs
• Fully integrated power solution for a CPU/SOC core and DDR-I memory ICs
• Lowest system cost and smallest footprint with just three external output capacitors
• Three linear regulators for VCORE (1.5A), VDDQ (1.5A), and VTT (0.5A, source-sink)
• VDDQ = 2.5V, VTT = VDDQ/2 ±25mV
• VCORE is adjustable, with a default output of 1.5V
• Over-temperature and reverse current protection
• Overcurrent protection for all regulators
• PSOP-8 package with integrated heat spreader
• Lead-free version available
