General Description
The Micrel MIC2178 is a 200kHz synchronous buck (stepdown) switching regulator designed for high-efficiency, battery-powered applications.
The MIC2178 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
600μA in skip mode
< 5μA in shutdown mode
? Current-mode control
Simplified loop compensation
Superior line regulation
? 100 duty cycle for low dropout operation
? Current limit
? Thermal shutdown
? Undervoltage lockout
Applications
? High-efficiency, battery-powered supplies
? Buck (step-down) dc-to-dc converters
? Palmtop computers
? Laptop computers
? Cellular telephones
? Hand-held instruments
? Battery Chargers
