Batteries/Simulation 060603
 (June 2006) Simulate Lithium Batteries With A NiMH Gel

This is a circuit which uses a single Nickel-metal hydride battery to provide an output with discharge characteristics of a Lithium-ion battery. While waiting to fulfill a battery lead-time problem, the circuit can be used to complete a product.

A step-up converter provides the higher Voltage, and power control capability utilizes a burst mode circuit to limit shutdown power consumption.
