MAX17501

60V, 500mA, Ultra-Small, High-Efficiency,

Synchronous Step-Down DC-DC Converter

General Description

Beneﬁts and Features

● Eliminates External Components and Reduce Total Cost

•ꢀ No Schottky-Synchronous Operation for High

EfﬁciencyꢀandꢀReducedꢀCost

The MAX17501 high-efficiency, high-voltage, synchronous

step-down DC-DC converter with integrated MOSFETs

operates over a 4.5V to 60V input voltage range. This

device is offered in a fixed 3.3V, 5V, or adjustable output

•ꢀ Internal Compensation and Feedback Divider for

3.3V and 5V Fixed Outputs

voltage (0.9V to 92%V ) while delivering up to 500mA

of current. The output voltage is accurate to within

±1.7% over -40°C to +125°C. The MAX17501 is available

in a compact TDFN package. Simulation models are

available.

•ꢀ All-Ceramic Capacitors, Ultra-Compact Layout

● Reduces Number of DC-DC Regulators to Stock

•ꢀ Wide 4.5V to 60V Input Voltage Range

•ꢀ 0.9V to 92%V Adjustable Output Voltage

•ꢀ Delivers Up to 500mA

The device features peak-current-mode control with

pulse-width modulation (PWM). Users can choose devices

with either pulse frequency modulation (PFM) or forced

PWM scheme. PFM devices skip pulses at light load

for higher efficiency, while forced-PWM devices operate

with fixed switching frequency at any load for noise sensitive-

applications. The low-resistance, on-chip MOSFETs

ensure high efficiency at full load and simplify the layout.

•ꢀ 600kHz and 300kHz Switching Frequency Options

•ꢀ Available in a 10-Pin, 3mm x 2mm TDFN Package

● Reduces Power Dissipation

•ꢀ PeakꢀEfﬁciencyꢀ>ꢀ90%

•ꢀ PFMꢀFeatureꢀforꢀHighꢀLight-LoadꢀEfﬁciency

•ꢀ ShutdownꢀCurrentꢀ=ꢀ0.9μAꢀ(typ)

● Operates Reliably in Adverse Industrial Environments

•ꢀ Hiccup-Mode Current Limit, Sink Current Limit, and

Autoretry Startup

A programmable soft-start feature allows users to reduce

input inrush current. The device also incorporates an

output enable/undervoltage lockout pin (EN/UVLO) that

allows the user to turn on the part at the desired input-

voltage level. An open-drain RESET pin provides a

delayed power-good signal to the system upon achieving

successful regulation of the output voltage.

•ꢀ Built-In Output-Voltage Monitoring (Open-Drain

RESET Pin)

•ꢀ Resistor-Programmable EN/UVLO Threshold

•ꢀ Adjustable Soft-Start and Prebiased Power-Up

•ꢀ High Industrial -40°C to +125°C Ambient Operating

Temperature Range/-40°C to +150°C Junction

Temperature Range

Applications

● Industrial Process Control

● HVAC and Building Control

● Base Station, VOIP, Telecom

● Home Theatre

Ordering Information/Selector Guide appears at end of data sheet.

● Battery-Powered Equipment

● General-Purpose Point-of-Load
