BM1707 - 2A Synchronous Step-Down Regulator

Download the BM1707 datasheet PDF. This datasheet also covers the BM1703 variant, as both devices belong to the same 2a synchronous step-down regulator family and are provided as variant models within a single manufacturer datasheet.

Description

The BM1703/BM1707 is a high efficiency current mode synchronous buck PWM DC-DC .

The internal generated 0.6V precision feedback reference voltage is designed for low output voltage.

Low RDS (ON) synchronous switch dramatically reduces conduction loss.

Features

  • ¾ Input Voltage Range: 2.5 to 5.5V ¾ Adjustable Output Voltage From 0.6V to VIN ¾ Precision Feedback Reference Voltage: 0.6V (±2%) ¾ Output Current: 2A (Max. ) ¾ Up to 95% efficiency ¾ Internal Fixed PWM Frequency: 1.5MHz ¾ Low Quiescent Current: BM1703=100μA,BM1707=45uA ¾ No Schottky Diode Required ¾ Built-in Soft Start ¾ Current Mode Operation ¾ Over Temperature Prot.

Bookly BM1703/BM1707 1.5MHz, 2A Synchronous Step-Down Regulator General Description The BM1703/BM1707 is a high efficiency current mode synchronous buck PWM DC-DC . The internal generated 0.6V precision feedback reference voltage is designed for low output voltage. Low RDS (ON) synchronous switch dramatically reduces conduction loss. To extend battery life for portable application, 100% duty cycle is supported for low-dropout operation. Shutdown mode also helps saving the current consumption. The BM1703 ( MSOP-10L) and BM1707(SOT23-5) to reduce PCB space. Pin to pin with AAT1145 , AAT1153 , AP2420 Features ¾ Input Voltage Range: 2.5 to 5.5V ¾ Adjustable Output Voltage From 0.6V to VIN ¾ Precision Feedback Reference Voltage: 0.6V (±2%) ¾ Output Current: 2A (Max.
