General Description
Features
The MAX15000/MAX15001 current-mode PWM con-
trollers contain all the control circuitry required for the
design of wide-input-voltage isolated and nonisolated
power supplies. The MAX15000 is well suited for uni-
versal input (rectified 85VAC to 265VAC) or telecom
(-36VDC to -72VDC) power supplies. The MAX15001
is well suited for low input voltage (9.5VDC to 24VDC)
power supplies.
The MAX15000/MAX15001 contain an internal error
amplifier that regulates the tertiary winding output volt-
age which is used in primary-side-regulated isolated
power supplies. Primary-side regulation eliminates the
need for an optocoupler. An input undervoltage lockout
(UVLO) is provided for programming the input-supply
start voltage and to ensure proper operation during
brownout conditions. An open-drain UVLO flag output,
with 210μs internal delay, allows the sequencing of a
secondary-side controller. The input-supply start volt-
age is externally programmable with a voltage-divider.
A UVLO/EN input is used to shutdown the MAX15000/
MAX15001. Internal digital soft-start eliminates output
voltage overshoot.
The MAX15000 has an internal bootstrap UVLO with
large hysteresis that requires a minimum 23.6V for start-
up. The MAX15001 does not have the internal bootstrap
UVLO and can be biased directly from a minimum volt-
