BA9737KV  
The BA9737KV is a 4-channel controller that includes all of the circuits required to construct a switching regulator. The  
circuitsonthechipincludeatriangular-waveoscillator, areferencevoltagecircuit, anerroramplifier, aPWMcomparator,  
a pseudo-totem-pole driver, and a short-circuit protection circuit.  
FApplications  
Camcoders and digital still cameras etc.  
FFeatures  
1) The totem-pole driver can directly drive power tran-  
sistors, andtheoncurrentcanbesettotheratingcur-  
rent using an external resistor.  
3) Channels 2 and 3 are supplied using the internal ref-  
erence voltage, and use a positive voltage only.  
Channels 1 and 4 are general-purpose channels,  
and all inputs are externally available.  
For the off current, the peak current can be set using  
an external capacitor.  
4) Channels can be switched off individually or all to-  
gether (STB and STB1 to STB4).  
2) Output cutoff circuit (timer latch type) for overload  
protection.  
5) Dead-time control is provided for all channels, and  
duty limits can be used.  
FAbsolute maximum ratings (Ta = 25_C)  
FRecommended operating conditions (Ta = 25_C)
