Product details
Overview
MAX710ESE+T from Maxim Integrated is a 3.3V/5V fixed-output, step-up/down DC-DC converter IC integrating a PFM-controlled boost stage and a low-dropout linear regulator in a single 16-pin narrow SO package. It operates from +1.8V to +11V input, delivers up to 500mA at 5V (VIN = 3.6V), achieves 85% typical efficiency in boost mode, and supports shutdown (0.2µA IQ) and standby (7µA IQ) modes for battery-powered portable equipment.
For engineers reviewing the MAX710ESE+T datasheet, MAX710ESE+T pinout, MAX710ESE+T application, or MAX710ESE+T equivalent, key selection criteria include its dual-mode operation (N/E pin configurable for high-efficiency or low-noise), preset 3.3V/5V output selection (3/5 pin), integrated LX switch and PFET pass element, and compatibility with single-cell Li+, multi-cell alkaline, and AC adapter–powered systems requiring stable low-voltage rails.
Technical Context
The MAX710ESE+T implements a hybrid architecture: a pulse-frequency-modulated (PFM) N-channel MOSFET boost converter (LX pin) sharing a precision 1.25V reference with a P-channel MOSFET linear regulator (PS-to-OUT path). Its N/E pin selects between high-efficiency mode (N/E = GND, linear regulator acts as low-RDS(on) switch during boost) and low-noise mode (N/E = PS, maintains ~0.5V headroom for ripple rejection).
Operation is controlled via dedicated logic inputs: SHDN enables full shutdown (input disconnected from output), STBY disables only the boost stage while retaining LDO regulation, and ILIM selects peak switch current limit (0.8A or 1.5A). The device includes an internal low-battery comparator (LBI+/LBI−/LBO) and supports output voltage selection via the 3/5 pin (GND = 5V, OUT = 3.3V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +1.8V to +11V - supports single-cell Li+ (2.7–4.2V), 2–4-cell alkaline (2.4–6.0V), and AC adapter inputs without external pre-regulation. |
| Output Voltage | Preset 3.3V or 5V - selected by tying 3/5 pin to OUT or GND; no external feedback resistors required. |
| Max Output Current | 500mA at 5V with VIN = 3.6V - sufficient for digital cameras, portable instrumentation, and microcontroller subsystems. |
| Quiescent Current | 7µA in standby, 0.2µA in shutdown - extends battery life in sleep/wake architectures. |
| Efficiency | 85% typical at 5V/250mA with VIN = 1.8V - enables usable runtime from deeply discharged batteries. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and extended-temperature portable applications. |
| Package | 16-pin narrow SO (SOIC-N) - industry-standard footprint with 0.154" width, compatible with automated assembly. |
Pinout & Package
MAX710ESE+T is housed in a 16-pin narrow SOIC (SOIC-N) package with standard 0.050" pitch and 0.154" body width. Pin 1 is marked with a notch or dot; thermal pad is not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LX (1, 16) | Internal N-channel MOSFET drain | Switch node connecting to external inductor; carries pulsed current up to 1.5A (ILIM = GND); requires short, low-inductance layout. |
| PGND (2, 15) | Power ground | Dedicated ground return for high-current boost path; must be connected to low-impedance ground plane separate from analog ground. |
| SHDN (4) | Shutdown control input | Active-low logic input; pulls OUT to GND and disconnects VIN when low; draws only 0.2µA in shutdown state. |
| ILIM (3) | Peak current limit select | Connect to GND for 1.5A limit (higher output power), or to PS for 0.8A limit (enables smaller, lower-cost inductors). |
| STBY (5) | Standby control input | Connect to GND to disable boost converter only; linear regulator remains active delivering 7µA quiescent current. |
| N/E (7) | Noise/Efficiency mode select | Connect to GND for high-efficiency mode (minimal forward drop during boost), or to PS for low-noise mode (0.5V headroom for ripple rejection). |
| 3/5 (6) | Output voltage select | Connect to GND for 5V output, or to OUT for 3.3V output; no external components needed for either setting. |
| LBO (8) | Low-battery comparator output | Open-drain output that goes low when LBI+ falls below LBI−; used to signal end-of-life battery condition. |
| LBI− (10), LBI+ (11) | Comparator inputs | LBI− typically tied to REF (1.25V); LBI+ monitors battery voltage via resistor divider; 50mV hysteresis prevents chatter. |
| PS (12) | Linear regulator source input | Primary power input for LDO stage; supplies internal circuitry and sets headroom for PFET pass element. |
| REF (13) | 1.25V precision reference output | Stable 1.25V reference for feedback and comparator use; requires 0.1µF bypass capacitor to GND for stability. |
| GND (14) | Analog ground | Low-impedance analog reference point; must be soldered directly to ground plane, separate from PGND traces. |
| OUT (9) | Regulated output | Final 3.3V or 5V output; requires 4.7µF capacitor to GND for LDO stability and 100µF for ripple filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated step-up/down conversion | Eliminates need for separate boost and LDO ICs; reduces BOM count and PCB area in space-constrained portable designs. |
| Configurable noise/efficiency trade-off | N/E pin allows real-time selection between 85% efficiency (N/E = GND) and superior ripple rejection (N/E = PS), adapting to dynamic load conditions. |
| Zero external FETs required | On-chip N-channel switch (LX) and P-channel pass transistor (PS→OUT) remove discrete MOSFETs, gate drivers, and associated layout complexity. |
| Ultra-low shutdown current | 0.2µA shutdown IQ enables multi-year shelf life in battery-backed devices such as medical sensors and IoT endpoints. |
| Battery-aware operation | Integrated LBI+/LBI−/LBO comparator provides programmable low-battery detection without adding external comparators or ADC resources. |

FAQ
What output voltages does the MAX710ESE+T support, and how are they selected?
The MAX710ESE+T supports fixed 3.3V or 5V outputs. Selection is made by the logic level on the 3/5 pin: tie to GND for 5V output, or tie to OUT for 3.3V output. No external resistors or programming are required. This simplifies design and eliminates calibration drift. The MAX710ESE+T maintains tight regulation (±3% over temperature and load) for both settings, as confirmed in the Electrical Characteristics table under "Output Voltage (MAX710)".
How does the N/E pin affect performance of the MAX710ESE+T?
The N/E pin configures the MAX710ESE+T for either high-efficiency or low-noise operation. When N/E = GND, the linear regulator acts as a low-RDS(on) switch during boost, maximizing efficiency (up to 85%). When N/E = PS, it maintains ~0.5V headroom for optimal ripple rejection-critical for noise-sensitive analog circuits. The MAX710ESE+T datasheet confirms this behavior in the Operating Configurations section and Typical Operating Characteristics plots.
What is the minimum input voltage required for the MAX710ESE+T to start up and regulate?
The MAX710ESE+T typically starts up with a 1V input, as stated in the Design Procedure section. However, full regulation depends on load and output voltage: for example, achieving 5V/250mA requires ≥1.8V input (per Absolute Maximum Ratings and Electrical Characteristics). The Minimum Start-Up Input Voltage vs. Load Current plot (TOC03) shows startup is possible down to ~1.0V at light loads, but stable regulation begins at 1.8V per specification limits.
Can the MAX710ESE+T be used with a 12V input?
No-the MAX710ESE+T has an absolute maximum input rating of +11.5V (PS, LX, OUT to GND), and the recommended operating input range is +1.8V to +11V. Applying 12V exceeds the Absolute Maximum Rating and risks permanent damage. The datasheet explicitly states "Input Voltage" max = 11.0V (Table, Electrical Characteristics), and all test conditions and curves assume ≤11V operation.
Does the MAX710ESE+T require an external Schottky diode, and why?
Yes-the MAX710ESE+T requires an external Schottky rectifier diode (e.g., Motorola MBRS130T3) connected between LX and OUT. Unlike synchronous rectifiers, the MAX710ESE+T uses an N-channel MOSFET for the boost switch but relies on an external diode for flyback current path. This is confirmed in the Applications Information section and Table 2 (Component Selection), where "RECTIFIERS (D1)" lists a Schottky diode as mandatory.
