1 / 19 page LM2650 www.ti.com SNVS133C – JUNE 1999 – REVISED APRIL 2013 LM2650 Synchronous Step-Down DC/DC Converter Check for Samples: LM2650 1 FEATURES DESCRIPTION The LM2650 is a step-down DC/DC converter 2 • Ultra High Efficiencies (95% possible) featuring high efficiency over a 3A to milliamperes • High Efficiency Over a 3A to Milliamperes load range. This feature makes the LM2650 an ideal Load Range fit in battery-powered applications that demand long • Synchronous Switching of Internal NMOS battery life in both run and standby modes. Power FETs The LM2650 also features a logic-controlled • Wide Input Voltage Range (4.5V to 18V) shutdown mode in which it draws at most 25 μA from the input power supply. • Output Voltage Adjustable from 1.5V to 16V • Automatic Low-Power Sleep Mode The LM2650 employs a fixed-frequency pulse-width modulation (PWM) and synchronous rectification to • Logic-Controlled Micropower Shutdown (IQSD ≤ achieve very high efficiencies. In many applications, 25 µA) efficiencies reach 95%+ for loads around 1A and • Frequency Adjustable up to 300 kHz exceed 90% for moderate to heavy loads from 0.2A • Frequency Synchronization with External to 2A. Signal A low-power hysteretic or "sleep" mode keeps • Programmable Soft-Start efficiencies high at light loads. The LM2650 enters and exits sleep mode automatically as the load • Short-Circuit Current Limiting crosses "sleep in" and "sleep out" thresholds. The • Thermal Shutdown LM2650 provides nodes for programming both • Available in 24-lead Small-Outline Package thresholds via external resistors. A logic input allows the user to override the automatic sleep feature and APPLICATIONS keep the LM2650 in PWM mode regardless of the load level. • Notebook and Palmtop Personal Computers An optional soft-start feature limits current surges • Portable Data Terminals from the input power supply at start up and provides • Modems a simple means of sequencing multiple power • Portable Instruments supplies. • Global Positioning Devices (GPSs) • Battery-Powered Digital Devices 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
