4.5V to 40V Input Automotive

Flyback/Boost/SEPIC Power-Supply Controllers

4/MAX105

General Description

Features

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

♦ Wide 4.5V to 40V Operating Input Voltage Range

♦ Operates Down to 2.5V (with Bootstrapped V_CC

Bias)

startup if V

is supplied by an external bias voltage.

♦ Current-Mode Control

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.

♦ Low 300mV, 5% Accurate Current-Limit Threshold

Voltage

♦ Internal Error Amplifier with 1% Accurate Reference

♦ RC Programmable 4% Accurate Switching

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.

Frequency

♦ Switching Frequency Adjustable from 15kHz to

500kHz (1MHz for the MAX15005A/B)

♦ External Frequency Synchronization

♦ 50% (MAX15004) or Adjustable (MAX15005)

Maximum Duty Cycle

♦ Programmable Slope Compensation

♦ 10µA Shutdown Current

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.

♦ Cycle-by-Cycle and Hiccup Current-Limit

Protection

♦ Overvoltage and Thermal Shutdown Protection

♦ -40°C to +125°C Automotive Temperature Range

♦ 16-Pin TSSOP or 16-Pin Thermally Enhanced

TSSOP-EP Packages

The input undervoltage lockout (ON/OFF) programs the

input-supply startup voltage and can be used to shut-

down the converter to reduce the total shutdown cur-

rent down to 10µA. Protection features include

cycle-by-cycle and hiccup current limit, output overvolt-

age protection, and thermal shutdown.
