3 Description

The LM21215A is a synchronous buck DC-DC

converter that delivers up to 15 A of output current at

output voltages as low as 0.6 V. Operating over an

input voltage range of 2.95 V to 5.5 V with ultra-high

efficiency, the LM21215A suits a wide variety of low

voltage systems. The voltage-mode control loop with

high gain-bandwidth error amplifier provides high

noise immunity, narrow duty cycle capability and is

easily compensated for stable operation with any type

of output capacitor, providing maximum flexibility and

ease of use.

The LM21215A features internal overvoltage

protection (OVP) and cycle-by-cycle overcurrent

protection (OCP) for increased system reliability. A

precision enable pin and integrated UVLO allow turnon

of the device to be tightly controlled and

sequenced. Startup inrush currents are limited by an

internally-fixed or externally-adjustable soft-start

circuit. An integrated open-drain PGOOD indicator

provides fault reporting and supply sequencing.

Other features include auxiliary voltage rail tracking,

monotonic startup into pre-biased loads, and

switching frequency synchronization to an external

clock signal between 300 kHz and 1.5 MHz for beatfrequency

sensitive and multi-regulator applications.

The LM21215A is offered in a thermally-enhanced

20-pin HTSSOP package with an exposed pad that is

soldered to the PCB to achieve a very low junction-toboard

thermal impedance.
