Product Overview
The Texas Instruments TL5001CP is a monolithic pulse-width-modulation control circuit designed for power supply regulation in step-down, step-up, and flyback DC-DC converter circuits. Operating across a wide supply voltage range from 3.6 V to 40 V, it integrates an internal 1.0 V reference, error amplifier, soft-start circuit, undervoltage lockout, and short-circuit protection into an 8-pin plastic through-hole package.
Key Features
- Wide operating voltage range: 3.6 V to 40 V
- Oscillator frequency range from 20 kHz to 500 kHz
- Internal precision 1.0 V reference voltage
- Built-in undervoltage lockout (UVLO) and short-circuit protection (SCP)
- Wide dynamic duty cycle control up to 100%
- Open-collector output capable of driving external power bipolar transistors or MOSFETs
- Standard 8-pin dual in-line package (DIP-8) for through-hole assembly and socketing
Applications
- Custom benchtop power supply designs and buck or boost converter modules
- Component replacement and repair for industrial control boards and legacy instrumentation
- Breadboard prototyping of switch-mode power supplies without requiring surface-mount adapters
Frequently Asked Questions
What package style does the TL5001CP use?
The CP suffix designates Texas Instruments' standard 8-pin plastic dual in-line package (DIP-8) with standard 0.1-inch through-hole pin spacing.
What converter topologies are supported by this IC?
The device is built to control buck (step-down), boost (step-up), and inverting/flyback switch-mode power conversion circuits.
Why buy individual components here rather than a bulk surplus lot?
You can buy the exact count needed for your project or repair without purchasing large reels or lots filled with excess inventory. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, qualify for free shipping at $28, and ship same or next business day from our Idaho warehouse.
Breadboard-friendly through-hole DIPs keep switch-mode design hands-on and repairable. Plug it into a socket, set your timing resistor, and put clean regulated power right where the circuit needs it.
