Dual, 5A, 1.5MHz Step-Down
Regulator with Integrated High-Side Switches
General Description
The MAX8653 dual-output, synchronous, step-down reg-
ulator contains low R
DS(ON)
integrated high-side
MOSFET switches for ease of layout and achieving small
footprints. Each output delivers up to 5A. The output
voltage is adjustable down to 0.6V and operates from a
9V to 14V input voltage. The MAX8653 uses a proprietary
high-bandwidth, constant-frequency, peak-voltage-mode
control architecture and operates at an adjustable switch-
ing frequency between 300kHz to 1.5MHz. The architec-
ture is suitable for use with a wide range of output
capacitor technologies such as aluminum electrolytic,
POSCAPs, and ceramic capacitors for flexible design.
The simple compensation scheme achieves fast
response under both line and load transients.
The switching frequency is adjustable using a single
external resistor. The output channels operate 180° out-
of-phase to reduce the input ripple current, thus reduc-
ing the required input capacitance. The high operating
frequency minimizes the size of external components.
The external reference input (REFIN) enables imple-
mentation of tracking applications such as DDR power
supplies. The MAX8653 utilizes internal digital soft-start
and features a lossless (cycle-by-cycle) current sens-
ing. It includes adjustable, hiccup-mode current-limit
and short-circuit protection for minimum power dissipa-
tion under fault conditions. Each output contains an
enable (EN_) input along with a power-good (POK_)
signal for easy sequencing. The MAX8653 is available
in a 28-pin, 5mm x 5mm Thin QFN package.
