Description and Introduction

Dual, Current-Limited, High-Side P-Channel Switches with Thermal Shutdown The MAX895LESA is a DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on available data:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable (via external resistors)  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX895LESA is a high-efficiency, step-up DC-DC converter designed for low-power applications. It integrates a power switch and provides a regulated output voltage from a single-cell or dual-cell battery input. The device is optimized for portable electronics, such as wireless devices, PDAs, and other battery-powered systems.  

### **Features:**  
- **Low Quiescent Current:** 30µA (typical)  
- **Internal Power MOSFET:** Reduces external component count  
- **Pulse-Width Modulation (PWM) Operation:** Ensures stable output  
- **Soft-Start Function:** Prevents inrush current  
- **Undervoltage Lockout (UVLO):** Protects against low input voltage  
- **Small Footprint:** Suitable for space-constrained designs  

For exact performance characteristics, refer to the official datasheet from Maxim Integrated/Analog Devices.

Description and Introduction

Dual, Current-Limited, High-Side P-Channel Switches with Thermal Shutdown The MAX895LESA is a step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 30V  
- **Output Current:** Up to 500mA  
- **Switching Frequency:** 500kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX895LESA is a high-efficiency, step-down DC-DC converter designed for applications requiring a regulated, lower voltage from a higher input source. It integrates a power MOSFET switch and features a fixed-frequency PWM control scheme for stable operation.  

### **Features:**  
- **Adjustable Output Voltage** via external resistors  
- **Internal Power MOSFET** for reduced external component count  
- **Low Dropout Operation** for extended battery life  
- **Overcurrent Protection** to safeguard the circuit  
- **Thermal Shutdown** for overtemperature protection  
- **Low Quiescent Current** (typically 1.5mA)
