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

Synchronous Step-Down DC-DC Converter

General Description

Beneﬁts and Features

●ꢀ EliminatesꢀExternalꢀComponentsꢀandꢀReduceꢀTotalꢀ

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. It deliv-

ers output currents up to 500mA at output voltages of

•ꢀ Internal Compensation and Feedback Divider for

3.3V and 5V Outputs

0.9V to 92%V . The output voltage is accurate to within

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

able in a compact TDFN package. Simulation models are

available.

•ꢀ All-Ceramic Capacitors, Ultra-Compact Layout

●ꢀ ReducesꢀNumberꢀofꢀDC-DCꢀRegulatorsꢀtoꢀStock

The device features peak-current-mode control with

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

es 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 sensi-

tive-applications. The low-resistance, on-chip MOSFETs

ensure high efficiency at full load and simplify the layout.

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.
