The TL5001 and TL5001A incorporate on a single

monolithic chip all the functions required for a

pulse-width-modulation (PWM) control circuit. De-

signed primarily for power-supply control, the

TL5001/A contains an error amplifier, a regulator, an

oscillator, a PWM comparator with a dead-time-con-

reference voltage tolerance of ±3% compared to ±5% for the TL5001.

The error-amplifier common-mode voltage ranges from 0 V to 1.5 V. The noninverting input of the error amplifier

is connected to a 1-V reference. Dead-time control (DTC) can be set to provide 0% to 100% dead time by connecting

an external resistor between DTC and GND. The oscillator frequency is set by terminating RT with an external

resistor to GND. During low V

detailed description

voltage reference

A 2.5-V regulator operating from V

is used to power the internal circuitry of the TL5001 and TL5001A and as a

CC

reference for the error amplifier and SCP circuits. A resistive divider provides a 1-V reference for the error amplifier

noninverting input which typically is within 2% of nominal over the operating temperature range.

error amplifier

The error amplifier compares a sample of the dc-to-dc converter output voltage to the 1-V reference and generates

an error signal for the PWM comparator. The dc-to-dc converter output voltage is set by selecting the error-amplifier

gain (see Figure 1), using the following expression:

V

= (1 + R1/R2) (1 V)

Figure 1. Error-Amplifier Gain Setting

The error-amplifier output is brought out as COMP for use in compensating the dc-to-dc converter control loop for

stability. Because the amplifier can only source 45 µA, the total dc load resistance should be 100 kΩ or more.

oscillator/PWM

The oscillator frequency (f ) can be set between 20 kHz and 500 kHz by connecting a resistor between RT and

osc

GND. Acceptable resistor values range from 15 kΩ to 250 kΩ. The oscillator frequency can be determined by using

the graph shown in Figure 5.

The oscillator output is a triangular wave with a minimum value of approximately 0.7 V and a maximum value of

approximately 1.3 V. The PWM comparator compares the error-amplifier output voltage and the DTC input voltage

to the triangular wave and turns the output transistor off whenever the triangular wave is greater than the lesser of

the two inputs.

dead-time control (DTC)

DTC provides a means of limiting the output-switch duty cycle to a value less than 100%, which is critical for boost

and flyback converters. A current source generates a reference current (I ) at DTC that is nominally equal to the

DT

current at the oscillator timing terminal, RT. Connecting a resistor between DTC and GND generates a dead-time

reference voltage (V ), which the PWM/DTC comparator compares to the oscillator triangle wave as described

DT

in the previous section. Nominally, the maximum duty cycle is 0% when V is 0.7 V or less and 100% when V

DT

is 1.3 V or greater. Because the triangle wave amplitude is a function of frequency and the source impedance of

RT is relatively high (1250 Ω), choosing R for a specific maximum duty cycle, D, is accomplished using the

DT

following equation and the voltage limits for the frequency in question as found in Figure 11 (V max and V min

osc

are the maximum and minimum oscillator levels):

drops too low (approximately 3 V at 25°C) for proper operation. A hysteresis voltage of 200 mV eliminates false

triggering on noise and chattering.

short-circuit protection (SCP)

The TL5001/A includes short-circuit protection (see Figure 3), which turns the power switch off to prevent damage

when the converter output is shorted. When activated, the SCP prevents the switch from being turned on until the

internal latching circuit is reset. The circuit is reset by reducing the input voltage until UVLO becomes active or until

the SCP terminal is pulled to ground externally.

When a short circuit occurs, the error-amplifier output at COMP rises to increase the power-switch duty cycle in an

attempt to maintain the output voltage. SCP comparator 1 starts an RC timing circuit when COMP exceeds 1.5 V.

If the short is removed and the error-amplifier output drops below 1.5 V before time out, normal converter operation

continues. If the fault is still present at the end of the time-out period, the timer sets the latching circuit and turns

off the TL5001/A output transistor.

⁽¹⁾The marketing status values are defined as follows:

ACTIVE: Product device recommended for new designs.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.

NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in

a new design.

PREVIEW: Device has been announced but is not in production. Samples may or may not be available.

OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check

http://www.ti.com/productcontent for the latest availability information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements

for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered

at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and

package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS

compatible) as defined above.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame

retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,

or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information

published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a

the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
