DESCRIPTION
The Si9135 is a current-mode PWM and PSM converter
controller, with two synchronous buck converters (3.3 V and
5 V) and a flyback (non-isolated buck-boost) converter (12 V).
Designed for portable devices, it offers a total five power
outputs (three tightly regulated dc/dc converter outputs, a
precision 3.3-V reference and a 5-V LDO output). It requires
minimum external components and is capable of achieving
conversion efficiencies approaching 95%.
Along with the SMBUS interface, the Si9135 provides
programmable output selection capability.
The Si9135 is available in a 28-pin SSOP package and
specified to operate over the extended commercial (0°C to
90°C) temperature range.
