Current-Mode PWM Controllers with

Programmable Switching Frequency

General Description

Features

♦ Current-Mode Control

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.

♦ Programmable Switching Frequency Up to 625kHz

♦ Accurate UVLO Threshold (1%)

♦ Open-Drain UVLO Flag Output with Internal Delay

♦ 36V to 72V Telecom Voltage Range

♦ Universal Offline Input Voltage Range

Rectified 85VAC to 265VAC (MAX15000)

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.

♦ 9.5V to 24V Input (MAX15001)

♦ Digital Soft-Start

♦ Internal Bootstrap UVLO with Large Hysteresis

(MAX15000)

♦ Internal Error Amplifier with 1.5% Accurate

Reference

♦ 50µA (typ) Startup Supply Current

♦ 50% Maximum Duty-Cycle Limit

(MAX15000A/MAX15001A)

♦ 75% Maximum Duty-Cycle Limit

(MAX15000B/MAX15001B)

♦ 60ns Cycle-by-Cycle Current-Limit Propagation

Delay

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-

age of 9.5V.

♦ Available in Tiny 10-Pin µMAX Packages

TEMP RANGE

The switching frequency for the MAX15000/MAX15001 is

programmable with an external resistor. The MAX15000A/

MAX15001A provide a 50% maximum duty-cycle limit,

while the MAX15000B/MAX15001B provide a 75% maxi-

mum duty-cycle limit. These devices are available in 10-

pin µMAX^®packages and are rated for operation over the

-40°C to +85°C temperature range.
