GLOBAL STATE DIAGRAM
During normal operation TPS65200 is either in STANDBY mode or ACTIVE mode, depending on user inputs. In
STANDBY mode most functions are turned off to conserve power but the IC can still be accessed through I2C
bus and the current shunt monitor can be turned on and off. The bias system and main oscillator are turned off in
STANDBY mode.
The device enters ACTIVE mode whenever VBUS is asserted or the WLED driver is turned on. In ACTIVE mode
the main oscillator and reference system is turned on. The device will remain in ACTIVE mode as long as VBUS
remains high and/or the WLED driver is enabled.

LED DRIVER OPERATION
The TPS65200 offers a high efficiency, high output voltage boost converter designed for driving up to 10 white
LED in series. The serial LED connection provides even illumination by sourcing the same output current through
all LEDs, eliminating the need for expensive factory calibration. The device integrates 40-V/0.7-A switch FET and
operates in pulse width modulation (PWM) with 600-kHz fixed switching frequency. For operation see the block
diagram.
The LED driver can be enabled either through the CTRL pin or the WLED_EN bit in the CONTROL register. The
CTRL input is edge sensitive and should be pulled low at power-up. The CTRL pin allows PWM dimming of the
LEDs whereas the WLED_EN bit offers simple ON/OFF control only. The WLED_EN bit has priority over the
CTRL pin and when set to 1, the CTRL pin is ignored. If WLED_EN is set to 0 and the CTRL pin is low for
> 2.5 ms, the WLED driver is shut down.
The feedback loop regulates the FB pin voltage to the reference set by the VFB[4:0] bits in the WLED register
with a default setting of 200 mV. If any fault occurs during normal operation the driver is disabled, WLED_EN bit
is reset to 0 and the driver is put into FAULT state until the CTRL pin has been low for > 2.5 ms. The state
diagram for the WLED driver is shown in Figure 44.
