GENERAL DESCRIPTION
The 1496A is a fully integrated, high
efficiency 2A synchronous rectified step
down converter. The 1496A operates
at high efficiency over a wide output current
load range. This device offers two
operation modes, PWM control and PFM
Mode switching control, which allows a
high efficiency over the wider range of the
load. The 1496A requires a minimum
number of readily available standard
external components and is available in a
6-pin
