Detailed Description
The MAX1533A/MAX1537A standard application circuit
(Figure 1) generates the 5V/5A and 3.3V/5A typical of the
main supplies in a notebook computer. The input supply
range is 7V to 24V. See Table 1 for component selections
and Table 2 for component manufacturers.
The MAX1533A/MAX1537A contain two interleaved
fixed-frequency step-down controllers designed for low-
voltage power supplies. The optimal interleaved archi-
tecture guarantees out-of-phase operation, reducing the
input capacitor ripple. Two internal LDOs generate
the keep-alive 5V and 3.3V power. The MAX1537A has
an auxiliary LDO that can be configured to the preset
12V output or an adjustable output.
Fixed Linear Regulators (LDO5 and LDO3)
Two internal linear regulators produce preset 5V (LDO5)
and 3.3V (LDO3) low-power outputs. LDO5 powers
LDO3, the gate drivers for the external MOSFETs, and
provides the bias supply (V CC ) required for the SMPS
analog control, reference, and logic blocks. LDO5
supplies at least 100mA for external and internal loads,
including the MOSFET gate drive, which typically varies
from 5mA to 50mA, depending on the switching frequen-
cy and external MOSFETs selected. LDO3 also supplies
at least 100mA for external loads. Bypass LDO5 and
LDO3 with a 2.2μF or greater output capacitor, using an
additional 1.0μF per 20mA of internal and external load.
