EL7532数据手册集成电路（IC）的DCDC开关稳压器规格书PDF

描述 Description

The EL7532 is a synchronous, integrated FET 2A step-down regulator with internal compensation. It operates with an input voltage range from 2.5V to 5.5V, which accommodates supplies of 3.3V, 5V, or a single Li-Ion battery source. The output can be externally set from 0.8V to VIN with a resistive divider.
The EL7532 features PWM mode control. The operating frequency is typically 1.5MHz. Additional features include a 100ms Power-On-Reset output, 2 of PCB area with components on one side only. The package is specified for operation over the full -40°C to +85°C temperature range.
