Si9135
Vishay Siliconix
SMBus Multi-Output Power-Supply Controller
DESCRIPTION
FEATURES
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 both standard and lead (Pb)-free
28-pin SSOP packages and specified to operate over the
extended commercial (0 °C to 90 °C) temperature range.
