11 / 14 page 11 PAM2841 1.5A SW Current, 40V Precision WLED Driver , Power Analog Microelectronics Inc www.poweranalog.com Layout Considerations Layout Example Top Layer Bottom Layer As for all switching power supplies, especially those in high frequency and high current ones, layout is an important design step. If layout is not carefully done, the regulator could suffer from instability as well as noise problems. (1) Use separate traces for power ground and signal ground. Power ground and signal ground are connected together to a quite ground (input connector) (2) To prevent radiation of high frequency resonance, proper layout of the high frequency switching path is essential. Minimize the length and area of all traces connecting to the SW pin. The loop including the PWM switch, schottky diode and output capacitor, contains high current rising and falling in nanosecond and thus it should be kept as short as possible. (3) The input capacitor should be close to both the VIN pin and the GND pin in order to reduce the IC supply ripple. (4) Keep the signal ground traces short and as close to the IC as possible. Small signal components should be placed as close as possible to the IC, thus minimizing control signal noise interference. 08/2008 Rev 1.3 |
