69 / 104 page  3.57.5 OVERVOLTAGE PROTECTION 3.57.6 UNDER VOLTAGE LOCKOUT OPERATION 3.57.7 SM3 OUTPUT CURRENT - HIGH AND LOW CURRENT SETTINGS 3.58 RGB AND PWM DRIVERS 3.58.1 PWM PIN DRIVER TPS658620 Advanced Power Management Unit www.ti.com SLVS993 – OCTOBER 2009 The output voltage of the boost converter is sensed at pin SM3, and the integrated power stage switch is turned OFF when V(SM3) exceeds the internal over-voltage threshold V(OVP3). The converter returns to normal operation when V(SM3) < V(OVP3) – VHYS(OVP3). The power stage mosfet switch and the LED switch are open (off) when the TPS658620 enters the sleep mode or if the SM3 converter is set to OFF mode. A dedicated, open-drain pin (ISM3G) enables I2C selection of a low and high brightness setting for the SM3 output current, by modifying the external FB3 resistor value. See application diagram for details. This pin is configured as an open drain and it can be turned on/off with bit SM3_IGAIN on register SM3_SET1. The TPS658620 has integrated open drain and push-pull drivers with programmable duty cycle and frequency, targeted at driving external RGB drivers, keyboard LED's, vibrator motor and other system peripherals. Figure 3-20. RGB and PWM Driver Blocks The TPS658620 offers one high current (150mA max) open-drain PWM driver. The PWM driver is enabled when PWM_EN is 1 in register PWM. Table 3-41.
