Microchip Technology MIC2877 High Current Sync Boost Regulator
Microchip Technology MIC2877 High Current Sync Boost Regulator is a compact and highly efficient 2MHz synchronous boost regulator with a 6.5A switch. The regulator features a bidirectional true load disconnect function to prevent leakage current between the input and output when the device is disabled. The MIC2877 automatically operates bypass mode when the input voltage exceeds the target output voltage. The boost converter goes to PFM mode at light loads to improve efficiency. In shutdown mode, the regulator consumes less than 2uA. MIC2877 also features an integrated anti-ringing switch to minimize EMI, over-voltage and current protection, UVLO, and thermal shutdown. MIC2877 is available in an FTQFN22-8LD package with a junction temperature range of -40°C to +125°C.
