The ADP1621ARMZ-R7 is a fixed-frequency, pulse-width modulation (PWM), current-mode, step-up converter controller manufactured by Analog Devices. It is designed to drive an external n-channel MOSFET to convert input voltage to a higher output voltage. This controller supports various topologies including flyback, SEPIC, and forward converters, both isolated and non-isolated.
Key electrical specifications include an IC supply voltage range of 2.9 V to 5.5 V, with power-input voltage capability as low as 1.0 V. It boasts up to 92% efficiency and offers programmable operating frequencies from 100 kHz to 1.5 MHz. The device features ±1.0% initial accuracy, a maximum duty cycle of 97%, and a low shutdown current of 10 μA. Control features include enable and frequency control.
This controller is suitable for applications such as APD bias, portable electronic equipment, isolated dc-to-dc converters, step-up/step-down converters, LED drivers for laptops, and LCD backlighting. It operates within a temperature range of -40°C to 125°C (TJ).
The ADP1621ARMZ-R7 is available in a 10-MSOP package and supports surface mount installation. It is designed for positive output configurations and is isolation capable.
