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
