Data Sheets:
MIC2111B is a programmable-frequency, valley-current/voltage-mode PWM controller that provides the control and protection features necessary for power devices and drivers that use current sensing across the inductor. The MIC2111B can provide single tri-state PWM logic signal to work with either power-stage modules or discrete driver and MOSFETs. The device has precision enable and power-good (PG) functions for sequencing of multiple power supplies. In addition, the solution is compatible with intelligent power stages in a high-current, step-down DC/DC converter.To optimize system size and system efficiency, the MIC2111B frequency can be programmed from 200kHz to 2MHz. The device operates in power-saving mode at light loads by reducing frequency. Optional outside audio range operation is possible when the power-stage is configured in light load mode. The solution uses differential current sensing for better current-limit accuracy and a dedicated differential amplifier for remote output sensing for accurate output voltage control. The MIC2111B has a high-gain transconductance amplifier for loop compensation. External slope compensation can be added through a resistor to avoid sub-harmonic oscillations. Other features include programmable OCP, output OVP, and thermal OTP protections. The MIC2111B offers proprietary bi-directional, single wire fault communication for total system protection.The MIC2111B is available in a 20-pin 3mm x 3mm TQFN package and has a junction temperature range of -40°C to +125°C.
