EVALUATION KIT AVAILABLE

MAX17232/MAX17233

3.5V–36V, 2.2MHz, Synchronous Dual Buck

Controller with 20µA Quiescent Current

General Description

Beneﬁts and Features

● Eliminates External Components and Reduces Total Cost

•ꢀ No Schottky-Synchronous Operation for High

EfﬁciencyꢀandꢀReducedꢀCost

The MAX17232/MAX17233 offers dual synchronous step-

down DC-DC controllers with integrated MOSFETs. They

operates over a 3.5V to 36V input voltage range with 42V

input transient protection, and can operate in dropout

condition by running at 95% duty cycle. The controllers

can generate fixed output voltages of 3.3V/5V, along with

the capability to program the output voltage between

1V to 10V.

•ꢀ Simple External RC Compensation for Stable

Operation at Any Output Voltage

•ꢀ All-Ceramic Capacitor Solution: Ultra-Compact Layout

•ꢀ 180° Out-of-Phase Operation Reduces Output

Ripple and Enables Cascaded Power Supplies

● Reduces Number of DC-DC Controllers to Stock

•ꢀ Fixed Output Voltage with ±1% Accuracy (5V/3.3V)

or Externally Resistor Adjustable (1V to 10V)

•ꢀ 220kHz to 2.2MHz Adjustable Frequency with

External Synchronization

These devices use a current-mode-control architecture.

The devices can be operated 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 switching frequency. PFM operation disables

negative inductor current and additionally skips pulses at

light loads for high efficiency. The low-resistance, on-chip

MOSFETs ensure high efficiency at full load and simplify

the layout.

•ꢀ Frequency Synchronization Input

● Reduces Power Dissipation

•ꢀ 92%ꢀPeakꢀEfﬁciency

•ꢀ 8μAꢀ(typ)ꢀinꢀShutdown

•ꢀ 20μAꢀ(typ)ꢀQuiescentꢀCurrentꢀinꢀPFMꢀMode

The devices are available in a 28-pin TQFN-EP package

with exposed pad, and are specified for operation over

-40°C to +85°C.

● Operates Reliably

•ꢀ 42V Input Voltage Transient Protection

•ꢀ Cycle-by-Cycle Current Limit, Thermal Shutdown

•ꢀ Supply Overvoltage and Undervoltage Lockout

•ꢀ Power-OK Monitor

Applications

● Distributed Supply Regulation

● Wall Transformer Regulation

● General-Purpose Point-of-Load

•ꢀ Reduced EMI Emission with Spread-Spectrum Control

•ꢀ 50ns (typ) Minimum On-Time Guarantees PWM

Operation at Low Duty Cycle at 2.2MHz
