DESCRIPTION
XTR30010 is a family of small footprint PWM controllers de-
signed for extreme reliability and high temperature applications
such as DC/DC converters and PWM control. Being able to op-
erate from input voltages as high as 35V, XTR30010 PWM con-
trollers can run at frequencies as high as 800kHz, allowing the
use of small footprint and low-cost external passive components.
Functionality features include internal oscillator and voltage ref-
erence, programmable soft-start, voltage tracking, synchroniza-
tion capability, over-current protection and power-good flag.
Special design techniques were used to allow the XTR30010
parts to offer a precise, robust and reliable operation in critical
applications. Full functionality is guaranteed from -60°C to
+230°C, though operation well below and above this temperature
range is achieved.
Parts from the XTR30010 family have all functional features to
operate in buck, boost, buck-boost, flyback and push-pull modes.
Standard packaging options range from full-featured 24-lead
packages to small footprint 8-lead packages.
XTR30010 family parts have been designed to reduce system
cost and ease adoption by reducing the learning curve and
providing smart and easy to use features.
Parts from the XTR30010 family are available in ruggedized SMT
and thru-hole packages. Parts are also available as bare dies.

In this packaging configuration current mode control can be achieved by the addition of few external components.

This is the main overcurrent protection, based on a sense resistor from the low-side switch (or asynchronous rectifier) to PGND. A
second short circuit protection associated to the DCLimit terminal is also present. The short-circuit protection related to DCLImit is
based in detecting if the error amplifier is always working on its linear regime. This second protection is only efficient for strong short-
circuit conditions. For weak over current values, it will not trig or very lately, so that the power part could be damaged if the main short
circuit protection is not active.
4
Internally, DCLimit is set to 2/5VDD. Depending on the clock period and the saw-tooth slope, the maximum duty cycle can be limited
intrinsically. The range is however quite limited. Also, the saw-tooth slope and frequency are usually set by loop gain and stability con-
straints. Therefore, we consider here only the possibility of an independent control of the maximum duty-cycle, based on the availability
of the DCLimit pin.
5
DCLimit functionality is also used as a short-circuit protection. See “Over-current protection” in the “Theory of Operation” section.

LDrv is OFF when OCPMode and AsyncEnbl are both low.
