340KHz, 36V/3A Step-down Converter With Soft-Start

General Description

The LP6483S contains an independent 340KHz constant frequency, current mode, PWM step-down converters. The converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The converter can supply 3000mA of load current from a 4.5V to 36V input voltage. The output voltage can be regulated as low as 0.923V. The LP6483S can also run at 90% duty cycle for low dropout applications.
The LP6483S is available in a ESOP8 package and is rated over the -40℃ to 85℃ temperature range.
