Integrated Switches in 2mm x 2mm Package
General Description
The MAX15040 high-efficiency switching regulator
delivers up to 4A load current at output voltages from
0.6V to (0.9 x VIN). The device operates from 2.4V to
3.6V, making it ideal for on-board point-of-load and
postregulation applications. Total output-voltage accu-
racy is within ±1% over load, line, and temperature.
The MAX15040 features 1MHz fixed-frequency PWM
mode operation. The high operating frequency allows
for small-size external components.
The low-resistance on-chip nMOS switches ensure high
efficiency at heavy loads while minimizing critical parasitic
inductances, making the layout a much simpler task with
respect to discrete solutions. Following a simple layout
and footprint ensures first-pass success in new designs.
The MAX15040 incorporates a high-bandwidth
(> 15MHz) voltage-error amplifier. The voltage-mode
control architecture and the voltage-error amplifier per-
mit a Type III compensation scheme to achieve maxi-
mum loop bandwidth, up to 200kHz. High loop
bandwidth provides fast transient response, resulting in
less required output capacitance and allowing for all-
ceramic capacitor designs.
The MAX15040 features an output overload hiccup pro-
tection and peak current limit on both high-side (sourc-
ing current) and low-side (sinking and sourcing current)
MOSFETs, for ultra-safe operations in case of high out-
put prebias, short-circuit conditions, severe overloads,
or in converters with bulk electrolytic capacitors.
The MAX15040 features an adjustable output voltage.
The output voltage is adjustable by using two external
resistors at the feedback or by applying an external ref-
erence voltage to the REFIN/SS input. The MAX15040
offers programmable soft-start time using one capacitor
to reduce input inrush current. A built-in thermal shut-
down protection assures safe operation under all condi-
tions. The MAX15040 is available in a 2mm x 2mm,
16-bump (4 x 4 array), 0.5mm pitch WLP package.
