CFP TSSOP CFP CFP CFP
RT 1 1 1 1 1 I/O In internal oscillation mode, the RT pin must be populated with a resistor to AVSS. When the RT pin is floating, a 200-kHz to 4-MHz external clock is required at the SYNC pin. The frequency of the external clock must be twice the desired switching frequency.
PS 2 2 2 — — I/O Primary off to synchronous rectifier on dead-time set. Programmable through an external resistor to AVSS.
SP 3 3 3 — — I/O Synchronous rectifier off to primary on dead-time set. Programmable through an external resistor to AVSS.
LEB 4 4 4 — 4 I/O Leading edge blank time set. Programmable through an external resistor to AVSS.
HICC 5 5 5 5 5 I/O Cycle-by-cycle current limit time delay and hiccup time setting. Delay time and hiccup time determined by capacitor from HICC to AVSS. Connecting this pin to AVSS disables hiccup mode.
SYNC 6 6 6 6 6 I/O When the RT pin is floating, SYNC is configured as an input for a 200-kHz to 4-MHz external clock. In this case, the external clock input gets inverted and the system clock will run at half the frequency of the external clock input. When the RT pin is populated with a resistor to AVSS, SYNC outputs a 200-kHz to 4-MHz clock signal at twice the device switching frequency in phase with the switching of the device.
DCL 7 7 7 7 7 I/O Duty cycle limit configurability. For TPS7H5001-SP, connect to AVSS for 50% duty cycle limit, floating for 75%, and VLDO for 100%. For TPS7H5002-SP and TPS7H5003-SP, the DCL pin can be left floating or connected to VLDO to set the maximum duty cycle to 75% or 100%, respectively. For TPS7H5004-SP, this pin must be connected to AVSS in order to obtain the 50% maximum duty cycle.
EN 8 8 8 8 8 I Connecting the EN pin to the VLDO pin or external source greater than 0.6 V enables the device. In addition, input undervoltage lockout (UVLO) can be adjusted with two resistors.
VIN 9 9 9 9 9 I Input supply to the device. Input voltage range is from 4 V to 14 V.
OUTA 10 10 10 10 10 O Primary switching output A.
OUTB 11 11 — — 11 O Primary switching output B. Active only when DCL = AVSS.
SRB 12 14 — — — O Synchronous rectifier output B. Active only when DCL = AVSS.
SRA 13 15 13 13 — O Synchronous rectifier output A.
AVSS 14 16 14 14 14 — Ground of the device. The thermal pad, lid, and seal ring of the device are internally connected to ground for the ceramic package (CFP).
VLDO 15 17 15 15 15 O Output of internal regulator. Requires at least 1-μF external capacitor to AVSS.
CS_ILIM 16 18 16 16 16 I/O Current sense for PWM control and cycle-by-cycle overcurrent protection. An input voltage over 1.05 V on CS_ILIM will trigger an overcurrent in the PWM controller. The sensed waveform on CS_ILIM contains a 150-mV offset when compared to the COMP/2 voltage at the input of the PWM comparator.
FAULT 17 19 17 17 17 I Fault protection pin. When the rising threshold of the FAULT pin is exceeded, the outputs will stop switching. After the external voltage drops below the falling threshold, the device will restart after a set delay. Connect this pin to AVSS to disable FAULT.
REFCAP 18 20 18 18 18 O 1.2-V internal reference. Requires a 470-nF external capacitor to AVSS.
RSC 19 21 19 19 19 I/O A resistor from RSC to AVSS sets the desired slope compensation.
SS 20 22 20 20 20 I/O Soft start. An external capacitor connected to this pin sets the internal voltage reference rise time. The voltage on this pin overrides the internal reference. It can be used for tracking and sequencing.
VSENSE 21 23 21 21 21 I Inverting input of the error amplifier.
COMP 22 24 22 22 22 I/O Error amplifier output. Connect frequency compensation to this pin.
NC N/A 12, 13 11, 12 2, 3, 4, 11, 12 2, 3, 12, 13 — No connect. Can be connected to AVSS to avoid floating metal if desired.
