11 / 31 page IFBx > VIFB_OVP for 24~32 switching cycles? No (caused by transient) Yes Normal Operation Boost stops switching, disable the current sink with VIFBx < 0.5V Another string is no use? Yes (single string application, caused by transient) Another VIFBx < 0.5V? Yes (caused by open string or more than two LED diodes short in a string) No (dual string application, caused by transient) No Boost stops switching, current sink(s) keep on VIFBx < VIFB_OVP_hys? Yes (to recover boost switching) SW > VOVP for 16~32 switching cycles? No Yes Soft Start / Normal Operation Latch off 11 TPS61162D www.ti.com SLVSC13A – JULY 2013 – REVISED MARCH 2016 Product Folder Links: TPS61162D Submit Documentation Feedback Copyright © 2013–2016, Texas Instruments Incorporated Feature Description (continued) Figure 6. SW OVP Protection Action Figure 7. VIFBx OVP Protection Action 8.3.10 Overcurrent Protection The TPS61162D has a pulse-by-pulse overcurrent limit. The boost switch turns off when the inductor current reaches this current threshold, and it remains off until the beginning of the next switching cycle. This protects the TPS61162D and external components under overload conditions. 8.3.11 Thermal Shutdown An internal thermal shutdown turns off the device when the typical junction temperature of 160°C is exceeded. The device is released from shutdown automatically when the junction temperature decreases by 15°C. |
