description
The TL5001 and TL5001A incorporate on a single
NC
8
14
NC
monolithic chip all the functions required for a
9 10 11 12 13
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-
trol
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 V
CC
conditions, the UVLO circuit turns the output off until V
CC
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.
