TEXAS INSTRUMENTS  LM5022MM/NOPB  DC/DC Controller, Current Mode, 6V to 60V, 1 Output, Boost, SEPIC, 1.115MHz, VSSOP-10

Product Overview

The LM5022MM/NOPB is a Current-mode Boost and SEPIC Controller. The LM5022 is a high voltage low-side N-channel MOSFET controller ideal for use in boost and SEPIC regulator. It contains all of the features needed to implement single ended primary topologies. Output voltage regulation is based on current-mode control, which eases the design of loop compensation while providing inherent input voltage feed-forward. The LM5022 includes a start-up regulator that operates over a wide input range of 6V to 60V. The PWM controller is designed for high speed capability including an oscillator frequency range up to 2MHz and total propagation delays less than 100ns. Additional features include an error amplifier, precision reference, line under-voltage lockout, cycle-by-cycle current limit, slope compensation, soft-start, external synchronization capability and thermal shutdown.
  • 1A Peak MOSFET gate driver
  • 90% Duty cycle limit
  • Programmable UVLO with hysteresis
  • Cycle-by-cycle current limit
  • AC-coupled external synchronizable
  • Single resistor oscillator frequency set
  • Slope compensation
  • Adjustable soft-start
  • Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
