ELMOS Product catalog 10/2004 | 17 DC/DC Converter package SO 8 pinning Pin Name Description 1 PGND Driver power ground pin. Connect pin to the current sense resistor, the (-) terminal of the input capacitor and the (-) terminal of the output capacitor. Due to high currents, and high frequency operation of the IC, a low impedance circuit ground plane is highly recommended 2 AGND Analog ground pin. This pin provides a clean ground for the controller circuitry: The output voltage sensing resistors should be connected to this ground pin. This pin is connected to the IC substrate. Connect to the (-) terminal of the output capacitor 3 ISEN Current sense input pin. Voltage generated across an external sense resistor is fed into this pin. Filters extensive high-frequency noise 4 VFB Positive feedback pin. Connect to SMPS output via external resistor divider to set output voltage and is referenced to 1.22V. For best stability, keep VFB lead as short as possible and VFB stray capacitance as small as possible 5 ON Switch ON input. Tie this pin to ground to force the IC into idle mode. A voltage of VSM or higher switches the controller in operating mode 6 VS Main supply input. Filters out high-frequency noise with a 100nF ceramic capacitor placed close to the pin to PGND 7 VSM Internal 5V regulator output. The driver and all control circuits are powered from this voltage. Decouple this pin to PGND with a minimum of 4.7µF tantalum and 100nF ceramic capacitors 8 MDRV Drive output. Drives the gate of the external MOSFET between PGND and VSM. Connect the external MOSFET via a damping resistor to this pin 1 2 3 4 8 7 6 5 PGND AGND ISEN VFB MDRV VSM VS ON adjustable, wide input range 910.24/25/26 pfm controller |
