Freescale Semiconductor, Inc. ANALOG PRODUCTS PC33394 MULTI OUTPUT POWER SUPPLY The PC33394 is a multi-output power supply device with high speed CAN transceiver. The IC incorporates a step-up/step-down switching pre-regulator, which operates over a wide input voltage range from 3.5 V to 26.5 V with transients up to 45 V. • Automotive Control Module Supply • Communications and Networking The following low drop out linear regulators provide several different output voltages to supply the microcontroller core and I/O, FLASH memory, sensors and other circuits. Active reset circuitry protects the data coherency of the microcontroller any time one of the three core voltages goes out of regulation. • Industrial Control Module Supply Simplified Application Diagram • Set Top Boxes PC33394 • xDSL Module Supply BOOT VBAT VPP 5.0 V SW1 KA_VBAT VIGN VSEN SW2_G VPRE VDD3_3 5.0 V VREF1 5.0 V VREF2 5.0 V VREF3 VDDH FLASH Memory 3.3 V 5.0 V VDDL_B 2.6 V* 5.0 V / 3.3 V VPP VDDL_FB Microcontroller (MPC5xx) CS VKAM SCLK SPI Control Input VKAM_FB DI CANL SS SCLK MOSI MISO DO CANH KA_2.6 V* /PORESET /PRERESET /HRESET CANTXD CANRXD GND NOTE: * The VDDL and VKAM output voltages of the PC33394 can be adjusted by changing the external FB resistor ratios.
