technical note 28/29 bu ?? ta2wnvx series, bu ?? ta2whfv series www.rohm.com 2011.01 - rev.c ? 2011 rohm co., ltd. all rights reserved. notes for use ? about absolute maximum rating breakage may occur when absolute maximum ratings such as applied voltage and operating temperature range are exceeded. short mode or open mode cannot be specified at o ccurrence of a break, so please prepare physical safety measures (e.g., fuse) if such special mode in which the absolute maximum rating is exceeded can be assumed. ? about gnd potential please be sure that the potential of the gnd terminal is the lowest in any operating condition. ? about thermal design please provide thermal design with sufficient margin, taking power dissipation (pd) in actual usage conditions into consideration. ? about short between pins and misattachment please be careful regarding the ic direction and misalignment at attachment onto a printed ci rcuit board. misattachment may cause a break of ic. short caused by foreign matter be tween outputs, output and power supply, or gnds may also lead to a break. ? about operation in a strong electromagnetic field please note that usage in a strong electr omagnetic field may cause malfunction. ? about common impedance please give due consideration to wiring of the power sour ce and gnd by reducing common-mode ripple or making ripple as small as possible (e.g., making the wiring as thick and short as possible, or reducing ripple by l ? c), etc. ? about stby terminal voltage set stby terminal voltage to 0.3 v or less to put each channel into a standby state and to 1.5 v or more to put each channel into an operating state. do not fix stby terminal voltage to 0.3 v or more and 1.5 v or less or do not lengthen the transition time. this may cause malf unction or failure. when shorting the vin terminal and stby terminal for usage, the status will be ?stby=vin low? at turning the power off, and dischar ge of the vout terminal cannot operate, which means voltage may remain for a certain time in the vo ut terminal. since turning the power on again in this state may cause overshoot, turn the power on for use af ter the vout terminal is completely discharged. ? about overcurrent protection circuit output has a built-in overcurrent protection circuit, which prevents ic break at load short. note that this protection circuit is effective for prevention of breaks due to unexpected accidents. please avoid us age by which the protection circuit operates continuously. ? about thermal shutdown output is off when the thermal circuit operates since a tem perature protection circuit is built in to prevent thermal breakdown. however, it recovers when the temperature returns to a certain temperature. the thermal circuit operates at emergency such as overheating of ic. sinc e it is prepared to prevent ic breakdown, please do not use it in a state in which protection works. about reverse current for applications on which reverse current is assumed to flow into ic, it is recommended to prepare a path to let the current out by putting a bypass diode between the v in -v out terminals. about testing on a set board when connecting a capacitor to a terminal with low impedance for testing on a set board, please be sure to discharge for each process since ic may be stressed. as a countermeasure against static electricit y, prepare grounding in the assembly process and take sufficient care in transportation and storage. in addition, when connecting a capacitor to a jig in a testing process, please do so after turning the power off and remove it after turning the power off. fig.181 example of bypass diode connection reverse current vin gnd stby out
