Part Number: LM5001

Function: 1A Current Mode Non-Synchronous Switch Mode Regulator

Package: DIP 8 Pin, WSON 8 Pin

Manufacturer: Texas Instruments

Pinouts:

 

Description

The LM5001 high-voltage switch-mode regulator features all of the functions necessary to implement efficient high-voltage Boost, Flyback, SEPIC and Forward converters, using few external components.

This easy-to-use regulator integrates a 75-V N Channel MOSFET with a 1-A peak current limit. Current mode control provides inherently simple loop compensation and line-voltage feed-forward for superior rejection of input transients. The switching frequency is set with a single resistor and is programmable up to 1.5 MHz. The oscillator can also be synchronized to an external clock. Additional protection features include: current limit, thermal shutdown, undervoltage lockout and remote shutdown capability.

Features

1. Integrated 75-V N-Channel MOSFET

2. Ultra-Wide Input Voltage Range from 3.1 V to 75 V

3. Integrated High Voltage Bias Regulator

4. Adjustable Output Voltage

5. 1.5% Output Voltage Accuracy

6. Current Mode Control with Selectable Compensation

7. Wide Bandwidth Error Amplifier

8. Integrated Current Sensing and Limiting
