SIMPLE SWITCHER 42Vin, 0.6A Step-Down Voltage Regulator in SOT-23
LMR14206 www.ti.com SNVS733D –OCTOBER 2011–REVISED APRIL 2013 ® LMR14206 SIMPLE SWITCHER 42Vin, 0.6A Step-Down Voltage Regulator in SOT-23 Check for Samples: LMR14206 1FEATURES DESCRIPTION The LMR14206 is a PWM DC/DC buck (step-down) 2• Input Voltage Range of 4.5V to 42V regulator. With a wide input range from 4.5V-42V, • Output Voltage Range of 0.765V to 34V they are suitable for a wide range of applications • Output Vurrent up to 0.6A such as power conditioning from unregulated sources. They feature a low R (0.9Ω typical) • 1.25 MHz Switching Frequency DSON internal switch for maximum efficiency (85% typical). • Low Shutdown Iq, 16µA Typical Operating frequency is fixed at 1.25 MHz allowing the • Short Circuit Protected use of small external components while still being able to have low output voltage ripple. Soft-start can • Internally Compensated be implemented using the shutdown pin with an • Soft-Start Function external RC circuit allowing the user to tailor the soft- • Thin 6-Pin SOT Package (2.97 x 1.65 x 1mm) start time to a specific application. • Fully Enabled for WEBENCH® Power Designer The LMR14206 is optimized for up to 600 mA load current with a 0.765V nominal feedback voltage. PERFORMANCE BENEFITS Additional features include: thermal shutdown, V IN • Tight Accuracy for Powering Digital ICs under-voltage lockout, and gate drive under-voltage • Extremely Easy to Use lockout. The LMR14206 is available in a low profile 6- pin SOT package. • Tiny Overall Solution Reduces System Cost APPLICATIONS • Point-of-Load Conversions from 5V, 12V, and 24V Rails • Space Constrained Applications • Battery Powered Equipment • Industrial Distributed Power Applications • Power Meters • Portable Hand-Held Instruments System Performance Efficiency vs Load Current Efficiency vs Load Current V = 12V, V = 1.2V and 3.3V V = 24V, V = 1.2V and 3.3V IN OUT IN OUT 100 100 90 90 80 80 70 70 60 60 50 50 40 40 30 30 20 20 10 1.2Vout 10 1.2Vout 3.3Vout 3.3Vout 0 0 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.0 0.1 0.2 0.3 0.4 0.5 0.6 LOAD CURRENT (A) LOAD CURRENT (A) 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. 2All trademarks are the property of their respective owners.
