MAX17552/MAX17552A

60V, 100mA, Ultra-Small, High-Efficiency,

Synchronous Step-Down DC-DC Converter

with 22µA No-Load Supply Current

General Description

Beneﬁts and Features

● Eliminates External Components and Reduces Total Cost

• No Schottky—Synchronous Operation for High

Efficiency and Reduced Cost

The MAX17552/MAX17552A high-efficiency, high-voltage,

synchronous step-down DC-DC converters with integrated

MOSFETs operate over a 4V to 60V input voltage range.

The converters can deliver output current up to 100mA at

• Internal Compensation

output voltages of 0.8V to 0.9 x V . The output voltage

is accurate to within ±1.75% over the -40°C to +125°C

temperature range.

• Fixed Internal 5.1ms or Programmable Soft-Start

• All-Ceramic Capacitors, Ultra-Compact Layout

● Reduces Number of DC-DC Regulators to Stock

The devices employ a peak-current-mode control

architecture with a MODE pin that can be used to operate

the device in pulse-width modulation (PWM) or pulse-

frequency modulation (PFM) control schemes. PWM

operation provides constant frequency operation at all

loads and is useful in applications sensitive to variable

switching frequency. PFM operation disables negative

inductor current and additionally skips pulses at light

loads for high efficiency. The converters consume only

22µA of no-load supply current in PFM mode. The low-

resistance, on-chip MOSFETs ensure high efficiency at

full load and simplify PCB layout.

• Wide 4V to 60V Input Voltage Range

• Adjustable 0.8V to 0.9 x V Output Voltages

• Delivers Up to 100mA Load Current

• 100kHz to 2.2MHz Adjustable Switching Frequency

Range with External Synchronization

• Configurable Between PFM and Forced-PWM

Modes

● Reduces Power Dissipation

• 22µA No Load Supply Current

• Peak Efficiency > 90%

• PFM Feature for High Light-Load Efficiency

• 1.2μA (typ) Shutdown Current

The devices offer programmable switching frequency to

optimize solution size and efficiency. Programmable soft-

start allows the user to reduce the inrush currents. During

overload, the MAX17552 implements a hysteretic cycle-

by-cycle peak-current-limit protection scheme, while the

MAX17552A implements a HICCUP-type overload protec-

tion scheme to protect the inductor and the internal FETs.

An EN/UVLO pin allows the user to turn on/off the device

at the desired input-voltage level. An open-drain RESET

pin allows output-voltage monitoring. The devices operate

over the -40°C to +125°C industrial temperature range

and is available in a compact 10-pin (3mm x 2mm) TDFN

● Operates Reliably in Adverse Industrial Environments

• Peak Current-Limit Protection

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

RESET Pin

• Programmable EN/UVLO Threshold

• Monotonic Startup into Prebiased Output

• Overtemperature Protection

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

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

Temperature Range

and 10-pin (3mm x 3mm) μMAX packages. Simulation

models are available.

Ordering Information appears at end of data sheet.

Applications

● Industrial Sensors and Process Control

● 4mA–20mA Current-Loop Powered Sensors

● High-Voltage LDO Replacement

● Battery-Powered Equipment

● HVAC and Building Control

● General-Purpose Point of Load
