10-A, 28-V Integrated Buck Regulator with Programmable LDO

DESCRIPTION

FEATURES

The Vishay Siliconix SiC417 is an advanced stand-alone

synchronous buck regulator featuring integrated power

MOSFETs, bootstrap diode, and a programmable LDO in a

space-saving MLPQ 5 x 5 - 32 pin package.

•

High efficiency > 92 %

•

Internal power MOSFETs:

High-side R_DS(ON)= 27 mΩ

Low-side R_DS(ON)= 9 mΩ

The SiC417 is capable of operating with all ceramic solutions

and switching frequencies up to 1 MHz. The programmable

•

Integrated bootstrap diode

Integrated configurable 150 mA LDO with bypass logic

Temperature compensated current limit

Pseudo fixed-frequency adaptive on-time control

All ceramic solution enabled

frequency,

synchronous operation

and

selectable

power-save allow operation at high efficiency across the full

range of load current. The internal programmable LDO may

be used to supply 5 V for the gate drive circuits or it may be

bypassed with an external 5 V for optimum efficiency and

used to drive external N-channel MOSFETs or other loads.

Additional features include cycle-by-cycle current limit,

voltage soft-start, under-voltage protection, programmable

over-current protection, soft shutdown and selectable

power-save. The Vishay Siliconix SiC417 also provides an

enable input and a power good output.

Programmable input UVLO threshold

Independent enable pin for switcher and LDO

Selectable ultra-sonic power-save mode

Internal soft-start and soft-shutdown

1 % internal reference voltage

Power good output and over voltage protection

Halogen-free according to IEC 61249-2-21 definition

Compliant to RoHS directive 2002/95/EC
