The • Low I Shutdown (< 10 µA) Q control method is based upon current mode control using an emulated current ramp. Current mode • Drives Standard or Logic Level MOSFETs control provides inherent line feedforward, cycle-by- • Robust 3.5-A Peak Gate Drive cycle current limiting and ease of loop compensation. • Free-Run or Synchronous Operation to 1 MHz The use of an emulated control ramp reduces noise • Optional Diode Emulation Mode sensitivity of the pulse-width modulation circuit, allowing reliable control of very small duty cycles • Programmable Output From 1.215 V to 36 V necessary in high input voltage applications. The • Precision 1.5% Voltage Reference operating frequency is programmable from 50 kHz to • Programmable Current Limit 1 MHz. The LM25116 drives external high-side and low-side NMOS power switches with adaptive dead- • Programmable Soft Start time control. A user-selectable diode emulation mode • Programmable Line Undervoltage Lockout enables discontinuous mode operation for improved • Automatic Switch to External Bias Supply efficiency at light load conditions. A low quiescent current shutdown disables the controller and • 20-Pin HTSSOP Exposed Pad consumes less than 10 µA of total input current. • Thermal Shutdown Additional features include a high voltage bias regulator, automatic switch-over to external bias for 2 Applications improved efficiency, thermal shutdown, frequency • Automotive Infotainment synchronization, cycle-by-cycle current limit and adjustable line undervoltage lockout. The device is • Industrial DC-DC Motor Drivers available in a power enhanced 20-pin HTSSOP • Automotive USB Adapters package featuring an exposed die attach pad to aid • Telecom Servers thermal dissipation.
