Si C931 Vishay Siliconix 4.5 V to 18 V Input, 20 A micro BRICK® DC/DC Regulator Module Features - Versatile - Operation from 4.5 V to 18 V input voltage - Adjustable output voltage down to 0.6 V - Output voltage tracking and sequencing with pre-bias start up LINKS TO ADDITIONAL RESOURCES - ± 1 % output voltage accuracy from -40 °C to +125 °C - Highly efficient Design Tool Evaluation Boards Design Tools DESCRIPTION The Si C931 is a synchronous buck regulator module with integrated power MOSFETs and inductor. Its power stage is capable of supplying 20 A continuous current at up to 2 MHz switching frequency. This regulator produces an adjustable output voltage down to 0.6 V from 4.5 V to 18 V input rail to acmodate a variety of applications, including puting, consumer electronics, tele, and industrial. Si C931’s architecture supports ultrafast transient response with minimum output capacitance and tight ripple regulation at very light load. The device is internally pensated and no external ESR network is required for loop stability purposes. The device also incorporates a power saving scheme that significantly increases light load efficiency. The regulator integrates a full protection feature set, including output over voltage protection (OVP), cycle by cycle over current protection (OCP) short circuit protection (SCP) and thermal shutdown (OTP). It also has UVLO and a user programmable soft start. The Si C931 is available in lead (Pb)-free power enhanced Power PAK® MLP60-A6C package in 10.6 mm x 6.5 mm x 3 mm dimensions. APPLICATIONS - 5 V and 12 V input rail POLs - 95 % peak efficiency - 1 μA supply current at shutdown - 50 μA operating current, not switching - Highly configurable - Four programmable switching frequencies available: 600 k Hz, 1 MHz, 1.5 MHz, and 2 MHz - Adjustable soft start and adjustable current limit - Programmable modes of operation: forced continuous conduction or power save mode - Robust and...
