Description

INTRODUCTION:

The NCV8871 is an adjustable output non−synchronous boost

controller which drives an external N−channel MOSFET. The device

uses peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the gate

driver.

FEATURES:

• Peak Current Mode Control with Internal Slope Compensation

• 1.2 V ±2% Reference voltage

• Fixed Frequency Operation

• Wide Input Voltage Range of 3.2 V to 40 Vdc, 45 V Load Dump

• Input Undervoltage Lockout (UVLO)

• Internal Soft−Start

• Low Quiescent Current in Sleep Mode

• Cycle−by−Cycle Current Limit Protection

• Hiccup−Mode Overcurrent Protection (OCP)

For a detailed description of NCV8871, please refer the following link below:

Note: This schematic is “Live”, you can pan and zoom and you can move the waveform probes around and look at signals on any of the nets (i.e. “wires”) or within any of the components. You can also double click on components to see their parameter values. If you choose "View in systemvision.com", you'll be able to save a copy and then change and re-simulate the circuit as you please.
