SLVS638C – JANUARY 2006 – REVISED NOVEMBER 2014 TL2575, TL2575HV 1-A Simple Step-Down Switching Voltage Regulators
1 Features 3 Description The TL2575 and TL2575HV devices provide all the
active functions needed for a step-down (buck)
switching regulator in an integrated circuit. They
require four to six external components for operation.
They accept a wide input-voltage range of up to 60 V
(TL2575-HV) and are available in fixed output
voltages of 3.3 V, 5 V, 12 V, 15 V, or an adjustableoutput version. The TL2575 and TL2575HV devices
have an integrated switch capable of delivering 1 A of
load current, with excellent line and load regulation.
The device also offers internal frequency
compensation, a fixed-frequency oscillator, cycle-bycycle current limiting, and thermal shutdown. In
addition, a manual shutdown is available via an
external ON/OFF pin. 1 Fixed 3.3-V, 5-V, 12-V, and 15-V Options with
В±5% Regulation (Max) Over Line, Load, and
Temperature Conditions
Adjustable Option With a Range of 1.23 V to 37 V …
