Detailed Description
The MAX15038 high-efficiency, voltage-mode switching
regulator delivers up to 4A of output current. The
MAX15038 provides output voltages from 0.6V to 0.9 x
V IN from 2.9V to 5.5V input supplies, making it ideal for
on-board point-of-load applications. The output voltage
accuracy is better than ±1% over load, line, and tem-
perature.
The MAX15038 features a wide switching frequency
range, allowing the user to achieve all-ceramic-capaci-
tor designs and fast transient responses (see Figure 1).
The high operating frequency minimizes the size of
external components. The MAX15038 is available in a
small (4mm x 4mm), lead-free, 24-pin thin QFN pack-
age. The REFIN function makes the MAX15038 an ideal
candidate for DDR and tracking power supplies. Using
internal low-R DS(ON) (24m Ω for the low-side n-channel
MOSFET and 31m Ω for the high-side n-channel
MOSFET) maintains high efficiency at both heavy-load
and high-switching frequencies.
The MAX15038 employs voltage-mode control architec-
ture with a high bandwidth (28MHz) error amplifier. The
voltage-mode control architecture allows up to 2MHz
switching frequency, reducing board area. The op-amp
voltage-error amplifier works with type III compensation
to fully utilize the bandwidth of the high-frequency
switching to obtain fast transient response. Adjustable
soft-start time provides flexibilities to minimize input
startup inrush current. An open-drain, power-good
(PWRGD) output goes high when V FB reaches 92.5% of
V REFIN and V REFIN is greater than 0.54V.
The MAX15038 provides option for three modes of oper-
ation: regular PWM, PWM mode with monotonic startup
into prebiased output, or skip mode with monotonic
startup into prebiased output.
