General Description
BA9737KV General Description
The BA9737KV is a 4-channel controller that includes all of the circuits required to construct a switching regulator. The circuits on the chip include a triangular-wave oscillator, a reference voltage circuit, an error amplifier, a PWM comparator, a pseudo-totem-pole driver, and a short-circuit protection circuit.

BA9737KV Features
The totem-pole driver can directly drive power transistors, and the on current can be set to the rating current using an external resistor. For the off current, the peak current can be set using an external capacitor.
Output cutoff circuit (timer latch type) for overload protection.
Channels 2 and 3 are supplied using the internal reference voltage, and use a positive voltage only. Channels 1 and 4 are general-purpose channels, and all inputs are externally available.
Channels can be switched off individually or all together (STB and STB1 to STB4).
Dead-time control is provided for all channels, and duty limits can be used.
BA9737KV Typical Application
Camcoders and digital still cameras etc.
