With an input Qualified for Automotive Applications range from 4.5 V to 42 V, they are suitable for a wide • AEC-Q100 Test Guidance With the Following: range of applications, such as power conditioning – Device Temperature Grade 1: –40°C to 125°C from unregulated sources. They feature a low R DSON (0.9‑Ω typical) internal switch for maximum efficiency Ambient Operating Temperature (85% typical). Operating frequency is fixed at – Device HBM ESD Classification Level 2 550 kHz (X option) and 1.25 MHz (Y option), allowing • Input Voltage Range of 4.5 V to 42 V the use of small external components while still being • Output Current Options of 100 mA, 300 mA, and able to have low output voltage ripple. Soft start can 600 mA be implemented using the Shutdown (SHDN) pin with an external RC circuit allowing the user to tailor the • Feedback Pin Voltage of 0.765 V soft-start time to a specific application. • 550-kHz (X) or 1.25-MHz (Y) Switching Frequency The LM2840 and LM2840-Q1 are optimized for up to • Low Shutdown I : 16-µA Typical Q 100 mA, the LM2841 and LM2841-Q1 for up to • Short-Circuit Protected 300 mA, and the LM2842 and LM2842-Q1 for up to • Internally Compensated 600‑mA load currents. They all have a 0.765-V nominal feedback voltage. • Soft-Start Circuitry • Small Overall Solution Size (SOT-6L Package) Additional features include: thermal shutdown, V IN undervoltage lockout, and gate drive undervoltage • Create a Custom Design Using the LM2840 With ® lockout. The LM284x and LM284x-Q1 are available in the WEBENCH Power Designer a low-profile SOT-6L package. • (1) 2 Applications Device Information • Battery-Powered Equipment PART NUMBER PACKAGE BODY SIZE (NOM) LM2840, LM2840-Q1, • Industrial Distributed Power Applications LM2841, LM2841-Q1, SOT (6) 1.60 mm × 2.90 mm • Portable Media Players LM2842, LM2842-Q1 • Portable Hand-Held Instruments (1) For all available packages, see the orderable addendum at the end of the data sheet.
