MAX653CPA+
降压, 开关稳压器, 固定, 4V至11.5V输入, 3V/225mA输出, DIP-8
产品概述
The MAX653CPA+ from Maxim Integrated Products is a 3V/adjustable, high-efficiency, low IQ, step down DC to DC converter in 8 pin DIP package. The step down switching regulator provides high efficiency over a wide range of load currents, delivering up to 225mA. A current-limiting pulse-frequency-modulated (PFM) control scheme gives the devices the benefits of pulse-width-modulated (PWM) converter (high efficiency at heavy loads) while using only 10µA of supply current (vs. 2mA to 10mA for PWM converter). The result is high efficiency over a wide range of loads. The input range is 4V to 11.5V provides lower preset output voltage of 3V or the output can be user-adjusted to any voltage from 1.3V to the input voltage. It has an internal 1A power MOSFET switch, making them ideal for minimum-component, low and medium power applications.
- Low battery detection comparator
- Current limiting PFM control scheme
- Dropout voltage is 0.5V at IOUT = 100mA, L = 100µH
- Efficiency is 85% (IOUT = 100mA, L = 100µH)
- Switch on-time is 8.3µs and switch off-time is 17.2µs (V+ = 9V, VOUT = 3V)
- Operating temperature range from 0°C to +70°C
- 5V to 3.3V Conversion; 9V Battery to 5V, 3.3V, or 3V Conversion; High-Efficiency Linear Regulator Replacement; Portable Instruments and Handy-Terminals
