MAX15004A/B/MAX15005A/B
4.5V to 40V Input Automotive
Flyback/Boost/SEPIC Power-Supply Controllers
General Description
The MAX15004A/B/MAX15005A/B high-performance,
current-mode PWM controllers operate at an automo-
tive input voltage range from 4.5V to 40V (load dump).
The input voltage can go down as low as 2.5V after
startup if V CC is supplied by an external bias voltage.
The controllers integrate all the building blocks neces-
sary for implementing fixed-frequency isolated/noniso-
lated power supplies. The general-purpose boost,
flyback, forward, and SEPIC converters can be
designed with ease around the MAX15004/MAX15005.
The current-mode control architecture offers excellent
line-transient response and cycle-by-cycle current limit
while simplifying the frequency compensation.
Programmable slope compensation simplifies the
design further. A fast 60ns current-limit response time,
low 300mV current-limit threshold makes the controllers
suitable for high-efficiency, high-frequency DC-DC con-
verters. The devices include an internal error amplifier
and 1% accurate reference to facilitate the primary-side
regulated, single-ended flyback converter or nonisolat-
ed converters.
An external resistor and capacitor network programs
the switching frequency from 15kHz to 500kHz (1MHz for
the MAX15005A/B). The MAX15004A/B/MAX15005A/B
provide a SYNC input for synchronization to an external
clock. The maximum FET-driver duty cycle for the
MAX15004A/B is 50%. The maximum duty cycle can be
set on the MAX15005A/B by selecting the right combi-
nation of RT and CT.
