Designed primarily for power-supply control, the TL5001/A contains an error amplifier, a regulator, an oscillator, a PWM comparator with a dead-time-control input, undervoltage lockout (UVLO), short-circuit protection (SCP), and an open-collector output transistor. The TL5001A has a typical 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 VCC conditions, the UVLO circuit turns the output off until VCC recovers to its normal operating range. The TL5001C and TL5001AC are characterized for operation from – 20°C to 85°C. The TL5001I and TL5001AI are characterized for operation from – 40°C to 85°C. The TL5001Q and TL5001AQ are characterized for operation from – 40°C to 125°C. The TL5001M and TL5001AM are characterized for operation from – 55°C to 125°C.

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: VO = (1 + R1/R2) (1 V) Compensation Network R1 VI(FB) 3 COMP 4 FB TL5001/A – R2 + 8 GND To PWM Comparator Vref = 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 (fosc) can be set between 20 kHz and 500 kHz by connecting a resistor between RT and 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 (IDT) at DTC that is nominally equal to the current at the oscillator timing terminal, RT. Connecting a resistor between DTC and GND generates a dead-time reference voltage (VDT), which the PWM/DTC comparator compares to the oscillator triangle wave as described in the previous section. Nominally, the maximum duty cycle is 0 % when VDT is 0.7 V or less and 100 % when VDT 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 RDT for a specific maximum duty cycle, D, is accomplished using the following equation and the voltage limits for the frequency in question as found in Figure 11 (Voscmax and Voscmin are the maximum and minimum oscillator levels): POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 3 TL5001, TL5001A PULSE-WIDTH-MODULATION CONTROL CIRCUITS SLVS084F – APRIL 1994 – REVISED JANUARY 2002 dead-time control (DTC) (continued) R DT ǒ Ǔƪ ǒ + Rt ) 1250 Ǔ ) Voscminƫ D V oscmax – V oscmin Where RDT and Rt are in ohms, D in decimal ǒ Ǔ Soft start can be implemented by paralleling the DTC resistor with a capacitor (CDT) as shown in Figure 2. During soft start, the voltage at DTC is derived by the following equation: V DT [ IDTRDT 1– e ǒ ń –t R Ǔ C DT DT 6 DTC CDT TL5001/A RDT Figure 2. Soft-Start Circuit If the dc-to-dc converter must be in regulation within a specified period of time, the time constant, RDTCDT, should be t0/3 to t0/5. The TL5001/A remains off until VDT ≈ 0.7 V, the minimum ramp value. CDT is discharged every time UVLO or SCP becomes active. undervoltage-lockout (UVLO) protection The undervoltage-lockout circuit turns the output transistor off and resets the SCP latch whenever the supply voltage 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. 4 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TL5001, TL5001A PULSE-WIDTH-MODULATION CONTROL CIRCUITS SLVS084F – APRIL 1994 – REVISED JANUARY 2002 short-circuit protection (SCP) (continued) 2.5 V RSCP 185 kΩ 12 kΩ CSCP SCP 5 From Error Amp 1.5 V SCP Comparator 2 To Output Drive Logic Q1 Vref = 1 V SCP Comparator 1 Q2 Figure 3. SCP Circuit The timer operates by charging an external capacitor (CSCP), connected between the SCP terminal and ground, towards 2.5 V through a 185-kΩ resistor (RSCP). The circuit begins charging from an initial voltage of approximately 185 mV and times out when the capacitor voltage reaches 1 V. The output of SCP comparator 2 then goes high, turns on Q2, and latches the timer circuit. The expression for setting the SCP time period is derived from the following equation: V SCP ǒ Ǔ + (2.5 * 0.185) 1 * e–tń ) 0.185 t Where τ = RSCPCSCP The end of the time-out period, tSCP, occurs when VSCP = 1 V. Solving for CSCP yields: C SCP + 12.46 t SCP Where t is in seconds, C in µF. tSCP must be much longer (generally 10 to 15 times) than the converter start-up period or the converter will not start. output transistor The output of the TL5001/A is an open-collector transistor with a maximum collector current rating of 21 mA and a voltage rating of 51 V. The output is turned on under the following conditions: the oscillator triangle wave is lower than both the DTC voltage and the error-amplifier output voltage, the UVLO circuit is inactive, and the short-circuit protection circuit is inactive.

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. Addendum-Page 2 -40 to 125 PACKAGE OPTION ADDENDUM www.ti.com 14-Oct-2022 (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
