MIC2177規(guī)格書詳情
General Description
The Micrel MIC2177 is a 200kHz synchronous buck (step down) switching regulator designed for high-efficiency, battery-powered applications.
The MIC2177 operates from a 4.5V to 16.5V input and features internal power MOSFETs that can supply up to 2.5A output current. It can operate with a maximum duty cycle of 100 for use in low-dropout conditions. It also features a shutdown mode that reduces quiescent current to less than 5μA.
Features
? 4.5V to 16.5V input voltage range
? Dual-mode operation for high efficiency (up to 96
– PWM mode for > 200mA load current
– Skip mode for < 200mA load current
?100m?internal power MOSFETs at 12V input
? 200kHz preset switching frequency
? Low quiescent current
– 1.0mA in PWM mode
– 500μA in skip mode
– < 5μA in shutdown mode
? 100 duty cycle for low dropout operation
? Current-mode control
– Simplified loop compensation
– Superior line regulation
? Current limit
? Thermal shutdown
? Undervoltage lockout
Applications
? High-efficiency, battery-powered supplies
? Buck (step-down) dc-to-dc converters
? Cellular telephones
? Laptop computers
? Hand-held instruments
? Battery Charger
