FEATURES Current mode control for simple loop compensation Input voltage range: 2.7 V to 5.5 V Output voltage range: 0.8 V to 5.5 V Tri-Mode™ operation for high efficiency 550 kHz PWM operating frequency High accuracy over line, load, and temperature Micropower shutdown mode Space-saving MSOP-8 package APPLICATIONS Li-ion powered handhelds MP3 players PDAs and palmtops Consumer electronics 500 mA PWM Step-Down DC-DC with Synchronous Rectifier ADP3051 GENERAL DESCRIPTION The ADP3051 is a low noise, current mode, pulse width modulator (PWM) step-down converter capable of supplying over 500 mA to output voltages as low as 0.8 V. This device integrates a low resistance power switch and synchronous rectifier, providing excellent efficiency over the entire output voltage range and eliminating the need for a large and costly external Schottky rectifier. Its 550 kHz switching frequency permits the use of small external components. Current mode control and external compensation allow the regulator to be easily optimized for a wide range of operating conditions. The ADP3051 operates at a constant 550 kHz frequency at medium to heavy loads; it smoothly transitions into Tri-Mode operation to save power at light loads. A pincontrolled micropower shutdown mode is also included. The ADP3051’s 2.7 V to 5.5 V input operating range makes it ideal for both battery-powered applications as well as those with 3.3 V or 5 V supply buses. It is available in a space-saving, 8-lead MSOP package. VIN .
