71 / 104 page  3.58.3 LED_PWM DRIVER ON LED_SET[7:0] T (ms) = , if LED_SET[7:0] 254 32 £ (3-9) 3.58.4 RGB DRIVERS 3.58.5 RGB1 DRIVER TPS658620 Advanced Power Management Unit www.ti.com SLVS993 – OCTOBER 2009 The LED PWM open drain pin has the duty cycle set by a pulse width modulation circuit. The LED_SET register bits (7:0) set the pulse width value in 256 steps. The pulse width modulated output is not a single pulse of the selected duty cycle but a collection of semi-equally spaced pulses that sum to the required duty cycle, with repetition rate of 125Hz (typ) Table 3-45.

Three outputs are available for each driver (pins REDn, GREENn, BLUEn), with I2C selection of operation mode and LED current. The RGB1 driver is enabled when RGB1_EN=HI, in RGB1_GREEN register. Each RGB1 pin (RED1, GREEN1 or BLUE1) will sink the current selected by RGB1_ISET[1:0], RGB1_RED register. The RGB1 driver can be set in a flashing mode, the flash operation parameters are configured in register RGB1FLASH. During the flashing ON time the duty cycle for each driver can be set individually using control bits PWMIR[4:0], PWMIG[4:0] and PWMIB[4:0] on registers RGB1_RED, RGB1_GREEN and RGB1_BLUE. The modulated output is not a single pulse of the selected duty cycle but a collection of semi-equally spaced pulses that sum to the required duty cycle, with repetition rate of 160Hz (typ). The start of 1 of the modulated pulses on RGB1 can be phased by 200 µs from the others so that for duty cycles below 50% the ON times of 2 of the LEDs will not overlap. When RGB1_PHASE is 0 (RGB1_GREEN[6]), the Red and Blue are drivers are in phase and Green is out of phase. For RGB1_PHASE is 1 the Red and Green are in phase and Blue is out of phase. Table 3-46.
