LM2696
3A, Constant On Time Buck Regulator
General Description
The LM2696 is a pulse width modulation (PWM) buck regu-
lator capable of delivering up to 3A into a load. The control
loop utilizes a constant on-time control scheme with input
voltage feed forward. This provides a topology that has
excellent transient response without the need for compen-
sation. The input voltage feed forward ensures that a con-
stant switching frequency is maintained across the entire V
IN
range.
The LM2696 is capable of switching frequencies in the range
of 100 kHz to 500 kHz. Combined with an integrated 130 m
high side NMOS switch the LM2696 can utilize small sized
external components and provide high efficiency. An internal
soft-start and power-good flag are also provided to allow for
simple sequencing between multiple regulators.
The LM2696 is available with an adjustable output in an
exposed pad TSSOP-16 package.
