... Function Description The AT1736 consists of a high-performance step-up converter, two linear regulator controllers, five high-current operational amplifiers, and a gate-on pulse modulator. The step-up DC-DC converter generates the source-driver supply voltage. The two linear regulator controllers provide the regulated positive gate-on and negative gate-off supply voltages from external charge pumps ...

... AT1736 enables the internal fault timer. If the fault condition exceeds the fault-timer duration (200ms typical), then the AT1736 shuts down all the outputs except the reference. Once the fault condition is removed, cycle the input voltage (below the UVLO falling threshold) to reactivate the chip ...

... Power-Up Sequence The AT1736 goes through start-up sequence after power-up. When V UVLO threshold, the reference voltage starts to rise. After reference voltage reaches regulation, the step-up converter and linear regulators will start up with the soft-start procedure. Once the FB voltage reaches the reference voltage, the gate-on pulse modulator delay block is also enabled ...

... Output Voltages Setting The output voltages of step-up converter and linear regulators are set by each resistive voltage-divider as the Typical Application Circuit shown. The AT1736 applies a 1.233V feedback reference voltage at FBL pin of linear regulator, and the output voltage setting is according to the following equation: ⎛ ...

... The most critical aspect of the layout is the placements of the input bypass capacitors of pin IN, VDDOP, VPSRC and REF. They must be placed as close as possible to the AT1736 to reduce the input ripple voltage and noise coupling. 2. Power loops on the input and output of the converters should be connected with the shortest and widest traces as possible ...
