Product Description

The LM5116MH is a wide operating range current mode synchronous buck controller in 20 pin HTSSOP package. This controller is intended for step down regulator applications from high voltage or widely varying input supply. The control method is based upon current mode control utilizing an emulated current ramp. Current mode control provides inherent line feed forward cycle by cycle current limiting and ease of loop compensation. The use of an emulated control ramp reduces noise sensitivity of pulse width modulation circuit allowing reliable control of very small duty cycles necessary in high input voltage applications. The operating frequency is programmable from 50KHz to 1MHz. The LM5116 drives external high side and low side NMOS power switches with adaptive dead time control. A user selectable diode emulation mode enables discontinuous mode operation for improved efficiency at light load conditions.
Wide operating range from 6V to 100V
Less than 10µA low quiescent when shutdown
Drives standard or logic level MOSFETs
Emulated peak current mode and robust 3.5A peak gate drive
Supply voltage range from 4.75V to 15V
Maximum duty cycle is 98%
Programmable output from 1.215V to 80V
Precision 1.5% voltage reference
Programmable current limit, soft start and line undervoltage lockout
Operating temperature range -40°C to 150°C
This device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to MOS gates.
