The • Low I Shutdown (< 10 µA) Q control method is based upon current mode control utilizing an emulated current ramp. Current mode • Drives Standard or Logic Level MOSFETs control provides inherent line feed-forward, cycle-by- • Robust 3.5-A Peak Gate Drive cycle current limiting, and ease-of-loop • Free-run or Synchronous Operation to 1 MHz compensation. The use of an emulated control ramp • Optional Diode Emulation Mode reduces noise sensitivity of the pulse-width modulation circuit, allowing reliable control of very • Programmable Output from 1.215 V to 80 V small duty cycles necessary in high-input voltage • Precision 1.5% Voltage Reference applications. • Programmable Current Limit The operating frequency is programmable from 50 • Programmable Soft-Start kHz to 1 MHz. The LM5116 drives external high-side • Programmable Line Undervoltage Lockout and low-side NMOS power switches with adaptive dead-time control. A user-selectable diode emulation • Automatic Switch to External Bias Supply mode enables discontinuous mode operation, for • HTSSOP-20 Exposed Pad improved efficiency at light load conditions. A low • Thermal Shutdown quiescent current shutdown disables the controller and consumes less than 10 µA of total input current. • Create a Custom Design Using the LM5116 with the WEBENCH Power Designer Additional features include a high-voltage bias regulator, automatic switch-over to external bias for 2 Applications improved efficiency, thermal shutdown, frequency synchronization, cycle-by-cycle current limit, and • Automotive Infotainment adjustable line undervoltage lockout. The device is • Industrial DC-DC Motor Drivers available in a power enhanced HTSSOP-20 package • Automotive USB Adapters featuring an exposed die attach pad to aid thermal dissipation. • Telecom Servers (1) Device Information PART NUMBER PACKAGE BODY SIZE (NOM) LM5116 HTSSOP (20) 6.50 mm × 4.40 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
