controller
BA9736KV
The BA9736KV is a 6-channel controller that includes all of the circuits required to construct a switching regulator. The
circuits on the chip include a triangular-wave generator, a reference voltage circuit, an error amplifier, a PWM compara-
tor, a pseudo-totem-pole driver, and a variety of protection circuits.
Applications
VCR / cameras, digital still cameras, and other portable
equipment
Features
1) The totem-pole driver can directly drive power tran-
sistors, and the on current can be set to the rating cur-
rent using an external resistor.
2) Miss-operation prevention circuit for low-voltage input.
3) Output cutoff circuit (timer latch type) for overload
protection.
4) Channels 1 and 4 employ FETs, and have totem-pole
drivers that rectify synchronously with a chopper. The
duty offset of the chopper can be adjusted externally.
5) For channel control, by making STB low level, all
channels go off, and by making STB3 low level, chan-
nel 3 can be switched off independently.
6) Soft start is applied to all channels using an external
capacitor, and is synchronized with the rising edges
of STB and STB3.
7) VQFP64 package (0.5mm pitch).
