8 / 31 page STw4141 STw4141 pinout 7/30 B4 VOUT2 Output voltage 2 C4 GND Signal ground D4 EN Enable Input: EN = Low - Device in shutdown mode, EN = High - Enable device This pin must be connected either to VDD or GND. Table 1. STw4141 pin description (continued) Pin Symbol Description PGND pin This is the ground pin related to power signal. This pin should be connected to the board ground plane by short and wide track or multiply vias to reduce impedance and EMI. GND pins This is the ground pin related to analog signal. PVDD pin This pin is designed to provide power to the device. This path leads high currents. It should be wide and short to minimize track impedance to reduce losses and EMI. VDD pin This pin is designed to provide signal supply voltage to the device. There is no specific requirement for its related track design. VLX1/VLX2 pins External coil is connected on those pins. It should be placed as closed as possible to the device in order minimize resistances which cause looses. These paths lead high currents. VOUT1 pin3 It is the first output voltage of this device. This path leads high currents. It should be wide and short to minimize track impedance to reduce losses and EMI. VOUT2 pin It is the second output voltage of this device. This path leads high currents. It should be wide and short to minimize track impedance to reduce losses and EMI. FB1 pin Intended to measure VOUT1 voltage in order to ensure the regulation of this output. FB2 pin Intended to measure VOUT2 voltage in order to ensure the regulation of this output. ENABLE pin This is the enable pin of the device. Pulling this pin to ground, forces the device into shutdown mode. Pulling this pin to VDD enables the device. This pin must be terminated. MODE/SYNC pin The MODE/SYNC pin is a multipurpose pin which provides mode selection and frequency synchronization. The device can also be synchronized to an external clock signal from 600 kHz to 1.5 MHz by the MODE/SYNC pin. During synchronization, the mode is forced to PWM mode and the top switch turn-on is synchronized to the rising edge of the external clock. AUTO pin This pin allows the device to automatically switch from PWM to PFM mode following load on both 2 outputs. STATE pin This output pin informs user in which state the device is working: PWM or PFM mode. VSEL pin This pin is used to reduce VOUT2 (CORE) output voltage in order to reduce the processor power consumption when entering into sleep mode. |
