Product Overview

The LM5088MH-2/NOPB is a high-voltage non-synchronous Buck Controller features all the necessary functions to implement an efficient high voltage buck converter using a minimum number of external components. The LM5088 can be configured to operate over an ultra-wide input voltage range of 4.5 to 75V. This easy to use controller includes a level shifted gate driver capable of controlling an external N-channel buck switch. The control method is based upon peak current-mode control utilizing an emulated current ramp. The use of an emulated control ramp reduces noise sensitivity of the pulse-width modulation circuit, allowing reliable control of very small duty cycles necessary in high input voltage/low output voltage applications. The LM5088 switching frequency is programmable from 50kHz to 1MHz. The LM5088-2 provides a versatile restart timer for overload protection.
  • Emulated current mode control
  • Drives external high-side N-channel MOSFET
  • Low IQ shutdown and standby modes
  • High duty cycle ratio feature for reduced dropout voltage
  • Hiccup timer for overload protection
  • Reference accuracy
  • Wide bandwidth error amplifier
  • Single resistor oscillator frequency setting
  • Oscillator synchronization capability
  • Programmable soft-start
  • High voltage, low dropout bias regulator
  • Thermal shutdown protection
  • Green product and no Sb/Br
