The • Fixed 5-V Output LM2775 can supply up to 200 mA of output current • 200-mA Output Current over a 3.1-V to 5.5-V input range, as well as up to 125 mA of output current when the input voltage is as • Inductorless Solution: Only Requires 3 Small low as 2.7 V. At low output currents, the LM2775 can Ceramic Capacitors reduce its quiescent current by operating in a pulse • Shutdown Disconnects Load from VIN frequency modulation (PFM) mode. PFM mode can • Current Limit and Thermal Protection be enabled or disabled by driving the PFM pin to high or low. Additionally, when the LM2775 is in shutdown, • 2-MHz Switching Frequency the user can chose to have the output voltage pulled • PFM Operation During Light Load Currents (PFM to GND or left in a high impedance state by setting pin tied high) the OUTDIS pin high or low. The LM2775 has been placed in TI's 8-pin WSON, a 2 Applications package with excellent thermal properties that keeps • USB OTG the part from overheating under almost all rated • HDMI Power operating conditions. • Portable Electronics Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) LM2775 WSON (8) 2.00 mm × 2.00 mm (1) For all available packages, see the orderable addendum at the end of the datasheet. space space space Typical Application Circuit Load Regulation 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
