Applications

3.6-V to 40-V Operation Internal Undervoltage-Lockout Circuit Internal Short-Circuit Protection Oscillator Frequency: kHz to 500 kHz Variable Dead Time Provides Control Over Total Range Tolerance on Reference Voltage Available in Q-Temperature Automotive High-Reliability Automotive a single monolithic chip all the functions required for a pulse-width-modulation (PWM) control circuit. Designed primarily for power-supply control, the TL5001A 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%. The error-amplifier common-mode voltage ranges from V to 1.5 The noninverting input of the error amplifier is connected to a 1-V reference. Dead-time control (DTC) can be set to provide 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 CC conditions, the UVLO circuit turns the output off until V CC recovers to its normal operating range. The TL5001A is characterized for operation from C to 125 AVAILABLE OPTIONS (1) PACKAGED DEVICES (2) T A SMALL OUTLINE (D) (3) C to 125 C TL5001AQDRQ1 (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI web site at www.ti.com (2) Package drawings, thermal data, and symbolization are available at www.ti.com/packaging (3) The D package is available taped and reeled.

A resistive divider provides a 1-V reference for the error amplifier noninverting input which typically is within of nominal over the operating temperature range. 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 using the following expression: V O R1/R2) Figure 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 µ the total dc-load resistance should be 100 k Ω or more. The oscillator frequency osc can be set between kHz and 500 kHz by connecting a resistor between RT and GND. Acceptable resistor values range from k Ω to 250 k Ω The oscillator frequency can be determined by using the graph shown in Figure The oscillator output is a triangular wave with a minimum value of approximately 0.7 V and a maximum value of approximately 1.3 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. 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 DT 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 DT which the PWM/DTC comparator compares to the oscillator triangle wave as described in the previous section. Nominally, the maximum duty cycle is when VDT 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 DT 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 osc max and V osc min are the maximum and minimum oscillator levels): Where R DT and R t are in Ω D is in decimal Copyright 2005 2009, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): TL5001A-Q1

The TL5001A remains off until V DT 0.7 the minimum ramp value. C DT is discharged every time UVLO or SCP becomes active. The undervoltage-lockout circuit turns the output transistor off and resets the SCP latch whenever the supply voltage drops too low (approximately V at for proper operation. A hysteresis voltage of 200 mV eliminates false triggering on noise and chattering. The TL5001A includes short-circuit protection (see Figure 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 starts an RC timing circuit when COMP exceeds 1.5 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.

The output of the TL5001A is an open-collector transistor with a maximum collector current rating of mA and a voltage rating of 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.
