BD8606FV

System Power Supply for TV Series FET Controller Type 3ch System Power Supply ICs BD8606FV No.09034EAT02 ●Description BD8606FV has realized the high performance and reliability required as a power supply for thin-screen TV. Due to the high-speed load response, it is most suitable for TV-purpose processors with increasingly high performance, and due to the wide phase margin it leaves a good margin for board pattern & constant setting and so facilitates its application design. As a high-reliability design, it has various built-in protection circuits (overcurrent protection, output voltage abnormal protection, thermal protection, and off-latch function at the time of abnormality etc.), therefore as an advantage it does not easily damage in every possible abnormal condition such as all-pin short circuit test etc. and hence most suitable for thin-screen TV which requires the high reliability. ●Features 1) 3ch synchronous rectification step-down system DC/DC converter controller 2) 3ch independent ON/OFF. controllable 3) Soft start, soft off function 4) Concentrated protection control with built-in sequencer 5) Built-in low voltage protection function 6) Built-in overvoltage protection function 7) Built-in overcurrent protection function 8) Built-in RT terminal open/short protection function 9) Frequency setting by external resistance is available. 10) Protection condition is output from PDET terminal. 11) Built-in external reset output function www.rohm.com © 2009 ROHM Co., Ltd.

Analog circuit of Ch interlocked to each CTL terminal starts operation at ON control (on mode), and goes down to setting output voltage. Analog circuit of Ch interlocked to each CTL terminal should be standby at OFF control (off mode), and output voltage becomes 0V. Table 2 DC/DC converter controller ON/OFF function CTL1 terminal voltage Ch1 CTL2 terminal voltage Ch2 CTL3 terminal voltage Ch3 >VIHCTL1 ON control >VIHCTL2 ON control >VIHCTL3 ON control VIHCTL VIHCTL OFF 1.95V(typ) < 1.0V(typ) < 0.62V(typ) ON Disable < VIHCTL OFF ※Terminal FC abnormality protection function is enabled when SS terminal voltage of each Ch becomes more than 1.1V (typ) in the transition to ON control (during soft start). RT terminal open/short protection function RT terminal open/shot protection function off-latches all DC/DC converter controller by detecting open/short condition internally from RT terminal to prevent from output voltage error caused by abnormal oscillation of internal triangular wave at RT terminal open/short. RT terminal open/short protection function is regularly enabled after boot-up. RT terminal open/short protection function operates when error detection condition continues about more than 400μsec (typ). www.rohm.com © 2009 ROHM Co., Ltd.

VSSCLM VSSPON SS terminal VSSSTB+VSSSTB_HYS 0V about 50msec( typ) Figure 28 At soft start time-out Error detection (off latch) release method Each Ch DC/DC converter controller comes into off latch condition when protection function operates. Off latch can be released by the following method. Each Ch DC/DC converter controller becomes able to do ON control transition by releasing off latch. 1. Set all Ch CTL terminal voltage as < VILCTL and continue that condition about more than 200usec (typ). 2. Drop down power supply VCC to below 3.7V. www.rohm.com © 2009 ROHM Co., Ltd.
