Informations produit
Aperçu du produit
The MAX1653EEE+ is a high efficiency, PWM, step-down DC-DC controller in 16 pin QSOP package. BiCMOS, switch-mode power supply controller designed primarily for buck topology regulator in battery powered applications where high efficiency and low quiescent supply current are critical. Device achieve up to 96% efficiency and deliver up to 10A using a unique Idle Mode synchronous rectified PWM control scheme. It automatically switches between PWM operation at heavy loads and pulse frequency modulated (PFM) operation at light loads to optimize efficiency over the entire output current range. It also features logic-controlled, forced PWM operation for noise-sensitive applications.
- Supply voltage range is 4.5V to 30V
- Operating temperature range from -40°C to 85°C
- Pin compatible upgrades to popular MAX797
- Programmable soft start
- 99% duty cycle for lower dropout
- Quiescent supply current is 170µA
- Logic controlled shutdown is 3µA
- N-channel, synchronous rectified control
- Oscillator frequency of 150KHz at SYNC = 0 or 5V & 300KHz at SYNC = REF PWM switching
- Feedback voltage is 2.5V
